I had my rifle built around a specific bullet. It was built around 190 grain Nosler custom competition bullet I played with the following combinations:

60.0 RL-22
WLR
Winchester case
2835 fps from a 22.5 inch Rock 1/10 barrel

I settled on the following because it is more accurate:

55.6 H4350
WLR or BR2
Hornady match case
2730 fps

The RL22 is good for consistent 1/2 moa but the H4350 load has gotten me down in the .3s before out to 500. That's the furtherst I shot this load for measured groups.

24" barrel win m70

55.0 gr. IMR 4350, 180GR. Nosler Partion, CCI #200

2,749 fps avg. 15 shots, no pressure signs but Berger Manual says their max load was yielding 2700 fps.  Federal  Ammo published specs for their factory 180gr. Nos. Part load is 2,750 out of a 24" barrel.  I feel like I could get 2800fps safely and other people are but I don't see the need.

So far I have 4831, might pick up some 4350 and 4064.  

Also, something that came to mind is a question about zeroing and accuracy comparison at appropriate distance.  I'm told that for loads intended for 500+ that often measuring accuracy at 100 or 200 isn't useful because the bullet has to settle down in its flight first, that it's more accurate at 250-300 and beyond than closer.  True or not?  From what I read from the ballistics calculation I've done is that for me to shoot at 600, a 300 yd zero is useful, less than that not so much.

Not much evidence of those settling or going to sleep theories, at least nothing you can use.

Using a longer distance for load development is definitely a must if you actually think you will shoot competition or game at 500 or more yards.

A scope reticule can be used to make setting the zero at 300 a very fast way to go. One must learn to hold down in close shots and hold over at 400 and 500 etc.

For game that doesn't stand around and pose broadside for long in big openings, this is a valuable set up.

My Vanguard in 30-06 is the same with heating up.  I am even making it worse on myself by going to 125 grain Nosler Accubonds.  This was born out of a need for a rifle for my daughter to hunt with, couldn't fund a full rig at the time - the way I wanted to set her up so it started with youth loads.  Turns out it became a joy to shoot.  Now we are "sharing" the gun and working on precision loads.

To get those sub MOA and occasional clover leaf groups I used to shoot :

165 gr SGK
Winchester or Federal brass
43.7 gr H335
CCI Mag LR primer

Now we are looking at:

125 gr NAB
Nosler Brass
50.2 grains RL15 (Currently, still wringing that out)
CCI LR primers

I use exactly that same combo of bullet and powder and charge weight.  Those Nosler BTs are spooky accurate for a hunting bullet.  Lately, however, I am getting equal accuracy and better velocity with 63.0 grains (compressed) RL-22 with the same bullet.    24" barrel. Velocity is fully 150 fps higher. Right at 2,975-3,000 fps with a 165!   Might want to give it a try.  

Of course, all disclaimers apply.  Reduce 10% and work up.  It is a max load per Nosler, but shows no pressure signs in my rifle.
Link Posted: 8/2/2015 11:18:16 PM EDT
[#13]
180 grain Hornady SST
56 grains IMR 4350
Hornady match brass

Not sure of the velocity but my guess would be somewhere around 2700-2800 fps out of a 22" tube.

After ruining two bolts I have gone back to RL22. I had no signs of pressure when using H4350, no flat primers, no flow on the primer from the firing pin, no marks on the case head and no sticky bolt lift. The cases just had two holes near the primer  and the bolts were etched from the gas. This powder is too spikey for me and after ruining two bolts I am done. It didnt happened with every case but every now and then and the environmental temperature  didnt matter. It happened when cool and warm with the same components  and same hand weighed charge.  I can deal with the more temperature sensitivity of RL22...

Leaked around the edge of the primer? They've gotten better, but for a while, Winchester primers were bad about firing pin punctures and leaking around the edge.

Yup, sure did!  But it never did this with the RL22 loads and I suspect because the RL22 is lower pressure. I have about 4k Winny primers left and I have since started buying CCI's but Winny seems to be so easy to get in my parts, everyone has them...ALL of the tie.

My friend RocketmanOU and I use them.  Awesome bullets, insane BC, downside is they're so long they tend to be compressed loads.  IIRC, we're loading H4831SC (can't remember the charge weight) and getting about 2600fps. Awesome long-range bullet.  

Reloder 19 and 22 are both supposed to be good powders in the .30-06 for that bullet.  We've got some, we just haven't done any load testing yet.

I would suggest that the bolt etching is due to the Winchester primers, and not the powder.  Even though you are having better luck with a different powder, that limitation quite possibly would not be there with a different brand primer.  Here is some further discussion on it:


http://forums.thecmp.org/showthread.php?t=169345


(photo not mine)

There has never been a recall or official published list, though Winchester reportedly will replace yours if you are experiencing issues - on a one-on-one basis.  I suggest you contact them.  From various internet posters (i.e. not confirmed), the following lots may be in question (list not exclusive):

CLL555G
CCL435G
EHL067G
DHL774G
DFL717G
DHL788G
DAL594G
CAL401G
GEL250G

EAL234G
DNL836G
DNL837G
DHL766G
GFL284G
DGL741G
FEL255G

I have several thousand of Winchester large rifle primers, and have to say they are visually the worst quality primers I have ever had.   When you look at a box of primed cases, and see the spectrum of colors and tarnish all over the map even in the same box, it is not inspiring.  The flatten out very easily, but I've yet to have one of mine leak.  What I do know, is I will never buy a Winchester primers again.  Speculation is they got a bad lot of brass sheet-stock, but no confirmation.

I quit using Winchester rifle primers years ago when they went from the white packageing and plated cups to the blue packaging and no plating.

I found the new unplated primers were soft as hell and had trouble with flattened primers and piercing that I never had with the older ones. I still use the pistol primers for my lower pressure loads like .38 special and .45 ACP.

Worked up some loads using IMR 4350 using the OCW method and all well under moa. My starting load was 55.1 and I knew it would shoot well because many mentioned it was a node. I worked up in .3 increments  until I reached 56.0 which shot well but was about .80 moa whereas the rest were all under .5 and 55.1 being .27 for five shots. I'm going to play with seating depth with the 55.1 and see if I can improve on the load some but I'm happy with where it is really. The recipe :

55.1 grns IMR-4350
Winchester case
CCI 200 primer
Hornady  178 HPBT
3.351 coal

I forget what it is from the ogive but I have it wrote down. My chrony kept throwing error codes so I turned it off, maybe it was too cold at 31 degrees and overcast....

It's 56.5 grains of powder, with a COL of 3.285" (about 0.015" off the lands in my rifle, about 0.022" in lima's). After tuning the ballistics app (in the middle of the last match, because my tables were completely off ), it reports a muzzle velocity of 2663 fps. A drop tube and the short cut powder reduce the load compression. Overall, I'm really happy with the load.

My rifle (same as lima's except for the stock):

Quoted from  the link: "The latest generation of Winchester primers, with brass-colored cups, should be avoided for AR15 use. The old silver Winchester primers worked fine, but the current WSRs are soft and can be pierced more easily than CCI or Rem primers."

I had trouble with them from the first package of WSR's I bought back 12-13 years ago and quit using them. I do use the pistol primers for my .38's and .45's and still buy up any older plated primers I can find.

Took her on Tuesday out 900 and 1000 yards with another load combo IMR 4350 52.5 grains and 190 CC. This load shot very well but it was moving along a little slow according to Strelok (2605 FPS). It required 38.5 MOA to get to 1000 K but the groups were really nice and tight. Tighter then the guy next to me shooting a 6.5 built by the same smith that built my rifle. I know thats more of a shooter issue than a caliber one. I didn't take a camera with me to get a pic of the groups but I will next time.

 F.U. photobucket!

Seeing how I never posted a pic of her, it's an old crappy cellphone pic...

I still have a bunch of 190's and about 7 lbs of RL22 so once I go through it I will start looking at a ball powder because I am tired of weighing each charge. I will say the Redding BR3 is a nice measure but I still have to weigh each charge using the 4350, I have not tried it with RL22 yet. I'd like to be able to use my 550 like a progressive and speed things up some. I'm looking at  4000 MR and 208s, has anyone used this combo?

Bullets "settle down" in under 100 yards. There is no point in zeroing any farther than 100yds unless you are relying on point blank range rather than dialing elevation. 




Someone explain to me what happens to the bullet between 100 yards and 300 yards. It has already "settled down" so what makes a 1/2moa load at 100yards be anything other than that at 300 yards ( atmospherics aside)?
What is happening that you need to test a load at 300yards rather than 100yards?

All of my load testing is done at 100, I  shoot these loads to ranges out to 1100, there are never any surprises. A Chronograph will tell you if you are going to have bad vertical.

I bought 1k of the 208 AMAX before they dried up.  This is a load that is inside 3/4" at 100:

59.0 gr R22
CCI LRP
Federal cases only neck sized after first firing
3.34" COAL

This load is more accurate for me than my 178 gr HPBT loads i've worked up w 4064

I have casually taken it out to 600 so far and was over 60% hits on a 2/3 ISPC steel plate.  Misses were my own fault/inexperience with wind calls.

There are pics of this rifle in one of the precision rifle pic threads on here somewhere in an AICS1.0 chassis.

That's good to know, I just bought 2 cases of 210 SMKs from a member here  and I'm you going to work up a load using RL22. I have a tight necked match chamber so I'm not so sure I'll be able to get up to 59 grains with the 210s. I'm you g to work up from 57 or so and go up.

good luck

I was getting crunching of the powder when seating the bullet at 59.5, but 59.0 was the tightest groups when working up starting at 57.0

keep the thread updated with your finding and post pics!

Well...I started at 56 and went up to 59 using .5 increments, 56.5 shot a we'll rounded group around .5 moa . I started seeing ejector marks right at 57-58 grains but it went away at 58.5. Things started to tighten up again at 59.0 but the groups shifted to the right with a little vertical stringing. I never did get sticky bolt lift but the ejector marks are concerning. I don't know why they went away as the charges went up from 57.5. I also don't know why I didn't see flattened primers or flow? Temp was 87 and high humidity. I'm going to load up more at 56.5 and take it out to 1k to see what they do...

Interesting.....  I did not witness any casing marks when I was working up, or any pressure signs at all for that matter.....  I could have been happy w the results of any of my incremental loads above 56.0, but my 59.0's offered the best velocity also so it was an easy decision to stick with that load.

The dies I am using are marketed by RCBS as "match quality" and includes the micrometer seater die, but I'd hesitate to put them in the same breath as a die set the guys going for max accuracy and compete in serious matches use.........  Also, I'd hesitate to think that brass would have that much of an effect of your reduced case capacity(by way of earlier casing marks) unless you're using older military brass.  I would surmise that the Federal brass I'm using is relatively similar to Winchester or Remington, etc.  in regards to usable case capacity.

My temps were similar to yours.  It was probably 85* that afternoon, but I do have less than 20% humidity regularly in my location.

I am currently on military orders out of my home state, so I will have to bow out of giving more advice without referring to my notes.  Id rather not give you potentially dangerous, wrong info based on misremembering things.  If this thread is still going in a few months when I get back home for good off orders, I will shoot some more and report my findings.  

Good luck in the meantime.

well, I backed off to the 56.3 charge and then I decided to moly the bullets in order to back the pressure down more. I bumped the charge up a grain, so I'm at 57.3 with no pressure. The load is outstanding! I shot a 5 shot group that was just a hair under 5 inches at 1000 yards on Monday. Strelok says my velocity is 2677 fps, I was hoping to get as close to 2700 as possible but I knew that would be hard with a 22 inch barrel. All in all I'm happy with the load. Once I burn through these last 4 lbs of RL22, I'm going to pick up a can of 23 because it's supposed to be similar to 22 but temp stable.

Picked up a keg of 4451, is anyone using this powder?

No, but I would love a range report when you get the load worked up.

I load '06 mainly in hunting rifles.  For hunting at moderate range, I prefer the lighter 150 grain bullets.  They have done well with near max loads of either H4350 or RL-19 with either Nosler BT or Barnes TSX bullets.  The BT's are near match accuracy.  The TSX is surprisingly accurate for an all copper hunting bullet, hovering just over 1 MOA with either powder.

I’ve loaded some up and they’re on the bench waiting to go, I had scheduled a day off tomorrow but work is killing that idea. I may go out Friday if I can squeeze it in. I’m loading heavy match bullets so you might not be too interested in my report.
