I got it figured out.  Now I just need to sell all of this powder that I bought that didn't work.

What I settled on was Enforcer.  Shot multiple 5 workups without a hitch.

10.5" 1:8 barrel.  175 Gr. SMK 2.1" OAL CCI400

8.0 Gr.

995
985
993
989
983

8.5 Gr.

1064
1042
1039
1048
1063

9.0 Gr.

1123
1113
1112
1107
1109

9.5 Gr.

1174
1187
1176
1165
1179

Next chance that the weather cooperates, I'll go back with some different OAL's and see how things go with 8.5 grains.

I am right at 20 gr of 1680 in a 10.5" with 125 grain bullets.

Nosler 125 BT's with H110 powder 2157 fps with 17.5 grains with oal at 2.060" using LC cases and RP 7 1/2 primers. Hodgdon's max was at 17.8 grains and I started to see some pressure signs at 17.8 grains. Very accurate in my 16" AR. H110 same as Win 296.

Speer TNT Varmint Bullets 125 Grain Jacketed Hollow Point
Hornady InterLock 125 Grain SST
Both are flat based bullets so i prefer to load them conservatively and not push them to hard.

17.6 grain's of H110 for the TNT out of my 16 inch build
17.4 grain's of H110 for the SST out of my 8.5 inch build.
CCI # 41 primers
lake city brass.

Both loads work well in both guns i just prefer the HP moving a little faster out of the 16 inch rifle.

Picked up a CZ 527 Blackout. Dies are on the way; I've been reading about the options, what people have been using for loading subs, and I'm not seeing a very clear trend. This rifle will exclusively be used for subsonics, plinking but also some hunting (maybe close range coyotes, foxes, groundhogs, raccoons, etc..). We'll see how that goes, maybe I'd be willing to try using it for short range deer down the road too.

Anyway at the moment I'm looking for bullet and powder recommendations. Seems like a lot of guys prefer to shoot a mid-range size bullets out of their bolt guns, say 168-175s rather than the 220s. I'm looking for accuracy and quiet, if it's cheaper that's great too.

Based on a couple of things I've read, to start, I'm zeroing in on 175gr SMKs with Unique. Any reason to look elsewhere? Any advice is appreciated.

Thanks

Hope to get back into this soon.
I'm going to setup my loading equipment in a storage unit and hope for the best.

208 ELD question.

I was loading these and using a OAL if 2.250"

I picked up a box or Hornady "Black" 208 Amax, as something to get a idea how close I was to that load.

I just got the can for it, so now with real velocity numbers, I can fine tune the load.

With my load, adding the can didn't add anything to velocity
So that load is in the low 900's
(I was told expect aprox 10%)

The Hornady load is advertised at 1020fps muzzle and I'm at 1017 with a 10" barrel w/can

1st thing I did was measure the OAL...
2.200

So....

.050 shorter

The Amax and ELD IS the same other than the tip material, correct?

Heres my plan and would love some feedback.

Cut my load back .2gr and stuff them in .050 deeper. Load 5

Also load 5 @ my loading and stuff them .050 deeper , and check the numbers.

Maybe even bump my load up .2gr AND .050" deeper.

Had anyone noticed a difference in accuracy with OAL changes with ELD subs?

My untuned load without a can was...

208 ELD (m)
wolf primers
11.2gr of A1680
2.250" OAL

Whos shooting the 208 ELD with a can, and is willing to comment/ share what they may have learned?

What did I learn? Can made zero diff in numbers.

IN MY SBR WITH MY LOAD!!

As always dont do / load anthing you read online. Work up
View Quote
208 gr ELD
TULA primer
2.12 COAL
11gr Shooters World Black Out Powder (I use batting in my subs to hold the powder in place)
5 rounds: hi 995   Lo 951.  Avg 976

If you need powder, buy cfe blackout.  H110 didn't work for me at all suppressed and 9.5"barrel.

What “didn’t work”? Inaccurate? Inconsistent velocity? There’s a lot that can go sideways in reloading and more info would be appreciated.

Guys I'm noticing that there are now .300 BO specific magazines.

What's different about these compared to standard .223 magazines?

Do they somehow fix the need to use the .250" ogive, hump seating depth thing?

The Magpul 300 Blackout PMags have the feed ribs in a different location tha in the 5.56mm magazines, and I’m pretty sure dryflash3 is right about why.  I haven’t had a chance to play with the ones I got to see how the rib position affects feeding with various bullet weights, but I expect they’ll run just about anything with up to mag-length COAL.

I suggest you size to .310 after powder coating.

Lee doesn't make that size, I just opened up a .309 sizer.

Drill motor, dowel, 400 grit sandpaper. Stop often and size a bullet to check your progress. Good luck

Lee does make a .310. Cutom order. Does not take that long to get one.
Custom dies

ETA: it says lead time six weeks. I recall mine taking about two maybe three weeks.

If you are annealing cases before forming, how far up the neck would you anneal, just the neck or would you anneal the shoulder as well since I would be forming the shoulder...?

.309 to .310 isn't much. Measure often as you can put metal removed back on.

Takes about a half hour, or you can wait 6 weeks.

I didn't anneal a single case before forming and now have over 10 firings on those cases without a single issue.  I took unknown amount of times fired Winchester .223 cases and ran them through a FL 300 BLK sizing die with the expander removed.  Then I used a trimmer to get them close to final trim length.  Deburred, chamfered, and then FL sized again with expander and finally trimmed to size.  Another deburr and chamfer and loaded.

Done properly annealing is done by temperature.

You use a drop of 750 degree Tempilaq on the inside of the neck. Let dry it will be light blue in color.

As case turns and the torch flame is on the neck you watch for the dot of Tempilaq as case rotates.

After about 3-4 seconds it will be clear, that's when you stop heating and drop case into a pan to cool, do not drop in water.

For proper annealing case should air cool.

Compare your just annealed case to a 5.56 round that is factory annealed. Should look the same.

You get any silver color on the case, it's over annealed.

Tempilaq is a must have and a bottle lasts a long time. 750 Tempilaq

I should have given more details... I am salt bath annealing, and wondering to what depth should I immerse the cases... I am guessing about 3/16th of an inch or so...

What do you have for a brass trimmer, Quarterbore?

I take my .223 brass and run them in my 300 BLK die with the decapper removed.  Then, using my Forster case trimmer with the .223 guide in it, I trim down to just over max case length.  Back through the 300 BLK die with decapper and a final trim to size with the .308 guide in my Forster.  Chamfer and deburr thrown in the mix as well.

Noob questions (might as well be - I've forgotten a ton).  Righto - haven't reloaded for about 10 years.

I have a Lee single stage 'breech' press, and 5.56 Lee dies.   https://leeprecision.com/breech-lock-challenger-press.html

Are any of the Lee 5.56 dies also good for 300 AAC without resetting them, or should I just buy a whole new set (3-piece or 4-piece?) of 300 dies?  This will be for reloading factory brass, not for cut-down brass.

Edit: I see that the die sets now come with a powder dipper.  Does anyone use the powder dipper that comes with the Lee die kit?

Thank you in advance.

Good evening.

The 300 BO cartridge will be a totally different die set.

The 300 BO is based off the .223Rem case but the two are very different cartridges one being .224 caliber and the other being .308.

Ive been really impressed with what Ive seen from the Barnes 110 Tac-TX round on deer sized game and tried to order some from MidwayUSA last weekend. After finding out that they wont ship loaded ammo to their "brothers in arms/customers" in NY, I decided that I am going to dig out the reloading gear and try and slowly work my way back into it this summer. I wull be running the pills out of a 16" barrel Troy PAR.

Any good load data floating around out there for the 110 Grain Barnes Tac-TX bullet and W296 Powder? Any special precautions that need to be taken with once fired 300BLK brass? Should 300BLK be crimped?

What distance do you guys like to zero at for subsonics? I'm using a CZ527 bolt action and will only be shooting subsonics. For hunting and critters never farther than 150 yards most likely, and while I may occasionally use it for fun at ranges beyond that, it's not a priority and it would be rare.

Thank you.  These ones?  https://www.xtremebullets.com/308-s/48051.htm

I imagine that I would want to reload 110 grain bullets.  But, really, for two-gun practice or matches (I've never done a match yet) - if I decide to use that 300 platform instead of 5.56 - I guess cheap and even subsonic would be fine around here.

I watch Ian and Karl shoot two-gun matches out west, but they have huge tracts of open land to make distance shots a thing, where-as I can't imagine a 2-gun distance around here being over 70 yards or so.

I have tons of data and trigger-time with 300BO but none with Barnes 110gr Tac-TX.

110gr Hornady Z-Max bullets over 19.8gr Alliant 300MP powder, lit by a CCI450 primer has shredded one hole at 100yds out of many rifles.

110gr Hornady Z-Max bullets are amazingly accurate and really cheap. Don't let the funky zombie theme marketing fool you.

ETA: No special precautions that I'm aware of. No need to crimp if your dies expander ball is giving you good neck tension. I often use a Lee factory crimp die to give a really light crimp just because

I really like the feeling of uniformity that it gives me. Just my own OCD thing and totally optional.

I’m as frugal as they come; no hangups about using “cheaper” components especially when they have good lineage (that’s why all of my reloading gear is Lee . Thanks for the data.

I’m saving my Barnes brass for fancy loads.  My converted brass is fine for plinking and practice.

Since I had zero commercial brass to start with, my original loads were all with converted brass.  Work ups were (mostly) with LC cases.

I recommend checking out any load with different brass to see if it is brass-dependent.  SOME loads might be, particularly subs.

Got back from the range without any Chrono data for the Nosler 220 Subsonics.  I got all sensor #2 errors on my magnetospeed  8.5gr H110, CCI 400 Primers and handmade brass out of PMC 223 donors.

Last trip I couldn't get any of the mags I brought with me to cycle from the left side with them loaded to 2.1"

Good news,  Magpul 300blk magazine worked flawlessly

Bad news,  the 220's tumbled and hit about a two foot to the left at 100yds.

Ignore the rest of the bad groups the big ol' flat holes up top were the 220's
