[Last Edit: Altair] [#1]
I asked in another thread what load most people would like to see gel tested.  Since more people wanted to see the 100gr SGK I shot the block this morning with a 100gr SGK loaded over 22.0gr of H4198 which gave me a MV of 2496fps.  The block was 10 feet from the muzzle (per FBI protocol) and I checked the block calibration with a BB going 598fps (that was as close as I could get to 590fps with my BB gun).

Overall I think the bullet performed well.  My gel block was only 13" because the mold swelled in the middle, cutting about an inch off the overall length.  I used water jugs behind the block to catch the bullet and the bullet passed completely through one and was caught in the second, so the 100gr SGK might have a but too much penetration for the FBI standards for duty ammo.  For hunting, however, that isn't a bad thing.

I don't have measurements yet and I have to leave soon but when I get back tonight I'll try to take some measurements.  I'll also try and get some cleaner pics as the block was starting to get condensation from the humidity and it made it harder to see the cavity.

Right side:

Bullet:



BB penetration:


ETA:  I did some quick measurements.  

Neck Length = 1"
Cavity = 1" to 11"
Max cavity = 5.75" @ 4.75" of penetration
Penetration = 13" gel +2 water jugs
Retained Weight = 65.6gr (65.6%)
Recovered Diameter = Max .617", Min .589", Avg .603"

To compare
87gr Hot-Cor:
Neck Length 0"
Cavity 0" to 12"+
Max Cavity = 5.625"+ @ 5" penetration
Penetration = 12" of gel +1 water jug
Retained Weight = 21.1gr
Recovered Diameter = Avg .394"

I cut the block every 2" to get more accurate measurements.  I found small frag all along the wound track but the bulk of it was around 4-6" (3rd section) which also coincides with the maximum cavity.  I found the cavity started at about 1.5" (not quite as short as I initially thought) and extended to about 11".

Penetration.....Cavity
2"......................3.5"
4"......................6.125"
6"......................6.125"
8"......................5.25"
10"....................2.625"

Ran some loads today.
20" BBL.
All HBN coated.
No chrono yet. Will have that in a few of days
Work up these loads if you try them.

All with LC 09 brass which has a bit more capacity.
LC09 = 30.5 gr h20 in 25-223.

115 gr Berger at 2.35 in a milled out magazine.
Worked up from 23 gr to 25.2 gr of W748.
Quickload listed W748 as one of the better powders for my combination.

24-24.5 is civil, semi rounded primers etc.
25-25.2 flat primer, very minor swipes on a few cases, like nothing to worry about.
Last 2 shots were 3/4" at 25.2.

Quickload estimates right at 2500 fps with the 115 gr berger over 25.2 gr of W748 out of a 20" bbl which would = 840 FPE at 400 yards and 700 FPE at 500 yards.
0 at 200 2.3" high max, -10 at 300, -28 at 400, -58 at 500.
That said QL is wrong a lot of times.

80gr TTSX HBN COATED at 2.3 col, RL7, ran loads from 23gr to 25.1gr.
23 thru 24 gr civil, no pressure signs.
24.5 okay, flat primers and about max, but at 2.3 col and HBN coated.
24.6 2 fairly good swipes one okay primer one loose.
24.8 light swipes, very very flat primers
25 one blown primer, one okay but very flat, swipes
25.1 very very flat primers, Light swipes no brass flow.
Stopped there and did not shoot the 25.2 gr load.

I tested an 85gr Nosler BT over 22.5gr of H4198 at a MV of 2625fps from my 16" .25-223 today.  Here are some preliminary measurements, I'll section the block tonight if time allows for more exact numbers.

Neck Length = 0.75"
Max Cavity = 5.75" @ 4.75" penetration
Penetration = 12.5" gel + 1 water jug
Retained Weight = 24.2gr
Recovered Diameter = .455"

Right Side:


Top:


Bullet:


There was significant fragmentation starting almost immediately and continuing along the entire bullet track.  The 85gr Nosler looked more like the 87gr Hot-Cor than the 100gr Game King because the frag was larger and easier to see in the gel.  It penetrated over 12" but again my block was far too short to catch the bullet.  I really need to get that larger mold made soon.

Chrono results, 20" bbl AR15 90dF
All HBN coated
All LC 09 brass which has more capacity.

115gr berger over 25.2gr W748, 2385 FPS = 1795 FPS and 825 FPE at 350 yards if QT is correct.
Milled out magazine at 2.35. Flat primers but I think I can get 2400 out of it.
Was hoping to get 2450 at least, but it will take a different powder if at all possible.
Might try AA 2200

80gr TTSX over 24.3 gr RL7 at 2.3" = 2925 FPS

100 gr PH over 25.5gr H335 at 2.25 = 2670FPS

yes, the 25/233 is kicking ass.

What has the HBN coating done for you? IE, did you need .5 gn more powder for the same velocity?

Honestly I dont know what it is doing for me yet if anything.
I have not done a side by side comparison and doubt I will.
Mostly using it to keep the initial pressure spike down a bit.

I think I can get more speed out of the 80gr TTSX over Norma 200 if anybody ever stocks it this year.
AA2200 looks like a good match for the 115 gr Berger and should be good for more FPS, but I have never used it so not quite sure.
It might be too fast for that bullet.

Right now I am more interested in the 115 gr berger.

Hi Tammons,

I had the best luck with both velocity and accuracy using A1680 with the Barnes 80 TTSX (see page 46 of this post)

The few loads that I tried with W748 suggest that it is a bit too slow burning.  With the heavier bullets A2200 and H335 gave the best performance for me.

good luck with your load development. Keep us posted on how your loads work out.

Finally got around to sectioning the block and taking more accurate measurements.  Here's what I found:

Penetration - Cavity
2" - 3.5"
4" - 5.625
6" - 5.5"
8" - 3.875"
10" - 1"

I was right about the short neck length and the fragmentation, which you'll see below, was more impressive with this load than with the 100gr SGK.  Of course, penetration was less and retained weight was less due ot this as well.  Here are the pics:

0"-2"

2"-4"

4"-6"

6"-8"

8"-10"

10"-12"

I'm either gonna do the 75gr V-Max or the 80gr TTSX next.  One extreme or the other.  I still only have the short block mold so I'm leaning toward the 75gr V-Max.

great info Altair!.


Have a question for you guys, what lengths are you getting on once fired brass? From the datum to case head? What are you resizeing the case to?

1, 2, or 3 thousandths smaller than fired? Im starting to mess with the fine tuning of seating depths and "head space length"

Thanks

I shot a 75gr V-Max at 2853fps from my 16" .25-223 into a gel block today.  Unfortunately my camera is not working so no pics yet, but I'll get them as soon as possible.  

Not surprisingly the V-Max did not penetrate 12" (the only one so far from the .25-223 that I've tested).  Here are the quick measurements:

Neck Length - 0"
Max Penetration - 8.75"
Max Cavity - 5.75" @ 6.75" of penetration

I didn't see any large piece that I would consider the core still intact.  It appeared that the bullet completely fragmented into small pieces.  That is great for varmints, but clearly not a useful bullet for medium game hunting or self defense.

The BB penetrated 4.25" this time, which is on the upper end for calibration, so I may be nearing the end of this block's usable life.

I have no specific plans to as I can't imagine I'd get very usable velocities from bullets that heavy in a 16" AR.  I'm not against the idea if that is an incorrect assumption and someone has a few to send me with load data.

With the 117 GK Brent got 2330 fps with the 117 gr GK in a 16" bbl over H335.
I have a 20" so a bit more for me.

I got the 115 gr berger up to 2380 in a 20" bbl but that was over W748.
H335 or another powder should do better.
It has to be loaded at 2.35 min due to the ogive so I am running it in a milled out mag and can probably sneak it out a bit more.
I can get 6 in top with whatever else loaded on bottom at 2.3 in a CP Defense mag.

If my calcs are right, if I interpolate from Brents 117 gr max load and apply that to a long loaded 115 gr berger, I
should be able to hit 2450+ with a 20" bbl.

At 2450 that works out to 804 fpe at 400 yards.
Zero at 200, 2.5 max ht, -4 at 250, -10 at 300, -30 at 400.

Running some new 115 gr Berger loads tomorrow.

The ogive on the Sierra 117 GK is shorter than the 115 Bergers so you can seat the 117 Sierra GK to mag length (2.26").

I think these two, IE the 115 berger and 117 GK will be my go to rounds for hunting deer and hogs this year and I will see how they work out.

Will basically be hunting with 6 115 gr berger hunting bullets on top of 4 117 gr GK at 2.3 with a
backup mag or two of 117 GK. 5 for deer though.

The hogs are gone right now but should be back in a month or so.

Both have a SD of .25 which is good.

I'm going to try it again and see what happens but I have enough unmixed gel to make two more blocks so even when this one is finished I've got plenty more.  I also plan on ordering more when thsi runs out as I have lots of stuff I want to test.

Bingo

115 gr Berger hunting bullet Chrono results - 95dF.
Please work up your loads from a safe min especially if not HBN coating.
These are hot loads.

115 gr berger hunting bullet HBN coated.
LC 09 1X brass 30.5 cap (more than most other brass so beware)
CCI BR primers
AR15 - 20" 10 twist bbl
2.36 COL in milled out CP defense mag. Holds 6.
H355 powder

These were just a couple of shells each, so I need to load more at the upper end and run them again over a chrono, check for loose primer pockets etc.
25 gr is civil. Should be running at 55k - 57k
25.5 looks as if its running at about 60k and is good in my book for a max hunting load.

23gr - 2310
23.5gr - 2335
23.8gr - bad
24gr - 2385
24.5gr - 2433
25gr - 2487 - very light like minor swipe. Primer looks decent
25.5gr - 2510 - Light swipes fairly flat primers

At 2510 this puts the 25-223 into some serious range territory for this tiny shell.
Zero at 200, Max ht 2.4", 250 - 3.8", 300 -9.5", 400, -28"
850 FPE at 400 yards, 780 at 450, 715 at 500 yds
Mildot lines up pretty much out to 500 yards.

16" bbl would be about 2400 fps and 840 FPE at 350 yards with this .25 SD bullet.

26gr - 2550 - More flattened primers, swipes
26.3gr - 2590 - blown primers, swipes, case head expanded .004"  Assume this is at 65-70k.

Edit - The ogive is so long the lands on my rifle are at about 2.42 with the 115 berger.
I can load out to about 2.38 COL in this milled out magazine.

Should be able to get 2525 out of it maxed out at 2.38 COL and thats supersonic at sealevel out to....
950 yards - LOL
Mighty Mouse

That said I have run more QL numbers and will most likely run it at 2.38" col and 24.8gr of H335 which should be easier on the brass
and will give me about 2450-2460 and still over 800 fpe at 400 yards.

According to my ballistic calc in my rifle (at 2400fps as per your estimate)  at 400yds the berger 115 is still at 1724fps easily able to kill medium game. Has 35.5" drop and in 10mph drifts 15".

Bump it 100fps and youll get 500yd killing power No prob  I may have to pick some up and play with them

[Last Edit: tammons] [#31]
Pretty easy to mill out the magazine, well I did not mill it.

I just drilled a hole then cut out the sides with a dremel then smoothed out the edges with a dremel.
Used a CP Defense mag so I can load some 2.3 col loads under.

Although 2.35-2.36 is good, 2.38 col looks better and its easier to get a bullet puller on the bullet if you need to do that.

I am using a cav arms lower so not sure about another lower and max col.

With my loads at 2.36, 20" bbl 2400 is probably a good all around very safe load in brass with a measured 30.5 h20 capacity.
2450 also not too bad.
2500 is getting up there and not much room for error, IE about .8 gr more and I was blowing primers.

I think the 2510 load was running at about 62k Just guessing.

Also not sure how much HBN is actually affecting the pressures. It will be interesting to see how you fare.

All of those above are a case full so bullet setback should not be a problem.

I know this bullet comes apart, so not sure how it will work on pigs, but I am going to try it.
The 117 GK has a pretty high BC/SD too. BC = .410 SD = .25 I think so it would also work for a heavy bullet.

Thanks to Brent and his 117 gr GK load, I had little work to do on the 115 gr berger due to his previous work.



Link Posted: 8/30/2012 4:45:52 PM EDT
[#32]
A GS custom 100 gr HV might be worth looking into.
100 gr copper bullet but the BC is .466.
You could run it at about 2650 with a 20" bbl so it would shoot flatter
than the berger, but the FPE is about the same out to 400 yards.
Its a copper bullet so it would not come apart like the berger and its over $1 each.

Another bullet I have never seen before is a 100gr Cutting edge all copper bullet (I think) with a BC of .420
Also over $1 each.

The swift Scirroco 100 gr bonded bullet has a BC of .43 so maybe it would be a good one too.
Somebody here surely has run it.
50 odd pages is tough for me to look through.
About the same and good out to 350-400.
SD is .216 but its bonded

I had mine threaded 5/8-24 so any .308 style muzzle device will work.  What is "best" will be the same subjectively as it would be on any other caliber.  If you like a Smith Vortex on your 5.56 (as I do), you'll probably like it on your .25-223.  It may not be quite as efficient as it will be designed for a larger caliber, but I doubt it will make a huge difference.  

I knew I didn't want mine threaded 1/2-28 because I didn't want to run the risk of somewhere down the road (with my kids perhaps) someone putting a 5.56 muzzle device on it and creating an unsafe situation.

I generally use either a Smith Vortex on things I don't want to put a suppressor on or a YHM Phantom with suppressor threads for the things (up to .308 caliber) that I do want to put my suppressor on.

Have settled in my mind on an 18" medium contour with a rifle length gas system.


That its pretty much what my barrel its except I am runnin a midlength system  (i think)  lol

My barrel is an 18" medium contour with a midlength gas system.

Keep in mind, worriedman, that if you go with the rifle gas system you're likely going to need to experiment with the gas port size to get it running right. I don't know that there have been any 18" barrels with a rifle-length system released and tested in the wild.

Anyway, if you go with midlength gas, you can drill to our specs and save yourself some time and trouble.

Barrel ordered, along with the rest of the parts for the upper build.  On the road to a custom worked resize die, have a .25 Vikerman seat die already, so I will be good to go for single stage loading, will have to work up a set up for the Dillon.

Question, will my Lyman M dies expanding .223 case necks allow me to load brass I currently have?

The go to resizer is a Redding 223 S full length sizer die with a 25 cal expander and 25 cal busing.
The correct size is back in this thread. That works.

I use a 223 seater.
If you want a crimp seater you can use a 25 WSSM seater.

A lee 25 WSSM trimmer works, but its not quite the right length.
I use a modified 223 lee trimmer.

Be sure to get the case gage from 320pf.

I am running my loads on the ragged edge so I hand weigh all my loads.

Not surprisingly the V-Max did not penetrate 12" (the only one so far from the .25-223 that I've tested).  Here are the quick measurements:

Neck Length - 0"
Max Penetration - 8.75"
Max Cavity - 5.75" @ 6.75" of penetration

I didn't see any large piece that I would consider the core still intact.  It appeared that the bullet completely fragmented into small pieces.  That is great for varmints, but clearly not a useful bullet for medium game hunting or self defense.

The BB penetrated 4.25" this time, which is on the upper end for calibration, so I may be nearing the end of this block's usable life.


Sorry for the delay in pics and measurements.  My camera has been sitting in a car that was being treated for bed bugs (long story, it was a precaution after transporting someone infested with them at work) so it was unavailable until last week.  I did it at midnight Tuesday after getting home from work but had to be up at 5am to leave for an out of town conference Wednesday.  I just got back.

Anyway, the pics are below.  As you can see the 2-4" section was really torn up, more so than any of the other bullets tested.  The penetration wasn't impressive and there was no bullet to recover, it completely fragmented in the blocl.  I still haven't found my notes with the measurements but I'll add them when I find it.  

ETA:  Found my notes.  I was off on the max cavity with my quick measurement initially.  Turns out the cavity at 3" was just a hair bigger than the one at 6.75" and it was smaller between them.  Not sure why but you can easily see in the side pic and on the pic of the 2-4" section that the cavity at 3" had much mroe severe damage than just the temp cavity at 6.75" of penetration.

Neck Length = 0"
Total Penetration = 8.5"
Max Cavity = 5.875" @ 3" penetration

Penetration   Cavity
2"............5"
4"............5.125"
6"............5.75"
8"............3.5"


Right:

0-2"

2-4"

4-6"

6-8"

8"+

question for 320pf (at least I think it was 320pf)

re: the 117rn, you mentioned a few pages back that you were going to test some H335 powder...did you ever test that load yet?

I only ask because I have yet to find a local source for the A2200

Hi ocelott

The 117 gn bullet results are on page 51.  Here is a summary of that post.  Once I found that I could shoot the Sierra 117 GK. I never went back to the Horn 117 RN.  I think that you can use the load data for the 117 Sierra GK to get an idea of where to start and the potential of the Horn 117 RNs.  With the shorter bullet length (0.97") of the Horn 117 RN I would guess that you should get close to 2400 fps or better with the  Horn 117 RN.

If you dont mind, please send me your loads or a link to the page.

Thanks


You might also want to try the Sierra 117 BT GameKings.  They will fly better then the Hornaday 117 RN.

30 round p-mag. They all fed fine with not

jams. Here are the results that I have so

far.

IMR 8208 (16-inch 1:10 barrel)
Load____Vel (fps)
23.5gr___2200
24.0gr___2259
24.5gr___2310

Hodgdon BenchMark (16-inch 1:10 barrel)
Load____Vel (fps)
23.5gr___2214
24.0gr___2222
24.5gr___2339

This matches the ballistics of the old 25

-35 with a 20-inch barrel. Put this load

in a 20-inch barrel you should get

2400fps. This looks like a good eastern

woods or hog load.


Here is my most recent load data using A2200.  It seems like A2200 is the go to powder for this round.

Horn. 117 Round Nose bullets
A2200 (16-inch 1:10 barrel)
Load____Vel (fps)
22.0gr___2256
22.5gr___2298
23.0gr___2339
23.5gr___2389 Max Load
24.0gr___2442 May be Over Max for some barrels.

I will try and test some H335 this weekend.
