Getting started with the 300blk ...

Back with the carbine and pistol. Chrony (MS) 145GC (bll & PC) 2137 avg 14 ES. No leading. 170 PB PC pistol 858 avg ES 66, slower than I thought. Had some carbine loads in the pistol, 1980 fps. Blew one primer in Carbine load, could be loose PP. 135gr HiTek did fine in the 938 sig but still pulling right a bit.
Ordered another box of GCs.
Oh. target. Off hand, not to bad.

Have no idea where I got the 18.5gr H110/296 load! Old age I guess. Did check the blown primer case (17gr load) and sure enough, case head was 377 (hornady) vs 371 on a previous fired (proper load) case. PP looked oily black - different. Anyway, still on the ragged edge with this powder - I've used couple #s H110, no problem, guess this one is hotter. Anyway, 2 coats BLL (50/50 wax/alox - no spirits) appears to be good WAY above 2200 fps. When GC are used. From the 18.5gr target (still decent groups for me) I'd say it was above 2400 fps, still decent accuracy. So my comment basically, 2x BLL to replace PC for HV loads works fine. If you got oversized (bullet) nose, try it.

Got the carbine load set right, pistol 170PB goes faster now. Need to order some new bolt gas rings, these were stuck and look worn. Never changed any before. friend got out of surgery 1/2 hr ago, doing fine and stroke problem solved.

I've got a buddy on my deer lease that has recently purchased a 300BLK.
I've no first hand experience with the 300Blk, but am seriously considering purchasing one, just so I can enjoy reloading together with him. We're also talking about adding supressors to our arsenals.
We have many hogs on our deer lease and the paper company we lease from has stated, if we don't start killing them, they will bring in professional hunters.
I've read Ians exploits with hog hunting ( 300BLK, 458 Socom, 308, ect.)
I know it's been documented on this forum before, but what is the effective range, in regards to accuracy and killing power, of a suppressed 300BLK. Seems like it would be pretty limited.

Personally speaking Id limit myown ise with subs to within 60 yrds. I limit super to 125.
I have tried it out to 200. Its a VERY POOR killer that far. Inside 100 many DRT shots have occurred. @150-160 I had a bullet SKIP OFF THE LEG BONE!!!! Luckly he had his head down and the bullet entered the neck and severed the jugular.
I like the 300 allot, But I limit its use to 1-125 yrds MAX.

GOOD LUCK

I 'accidently' hit the 2x4 support with 170gr 900 fps @ 50. Went through most of it. Sub PF for BO will need heavier bullets. With 145gr I can get to 150 (2k fps) but it's not sub. Like Ian found, throwing rocks at hogs from 100 yds doesn't do much. I upped the 170gr pistol load to (I think) 1400 but still plan on 50-60 max. It's still flat there and has enough punch but not sure I can be accurate at longer distance. Too old for suppressor $ and wait. 100gr black tip and 125gr SST are supposed to be really good, 150 BO gold dot also.

A .308 or better, suppressed, is my personal solution unless hunting over bait at close range with high-quality night vision or thermal and can make brain shots. 300 BLK with 230 grain subs has .45 ACP muzzle energy at 100 yards and is easily brain-shot accurate at 200 yards with predictable drop.....but wild pigs don't sit still for you and the bullet flight time is so long that pinpoint hits are VERY difficult to make.

That's kinda what I already knew, although I didn't account for a long flight time.
We each have two stands on our lease.
I have one on a pipe line and the other on a tower line. Feeders are at 100 yards on the pipe line and 185 yards on the tower line, due to hills (stand on the hilltop, feeder in the valley/creek sections.
No problem for j-words in a .270 or 7 Rem Mag.
Too far for anything suppressed.
Thanks for the responses.

Speaking strictly of sound, a suppressor will not help much for follow-up shots. Even the most quiet weapon still creates bullet impact noise and frightens the whole herd immediately after the first shot. What a suppressor DOES do for you (especially with supersonic loads) is save your hearing, suppress the muzzle flash almost entirely (thus not blinding you or damaging your night vision optics), reduces the sound of the shot to a HV .22 LR level, and mitigates recoil so you can stay in the glass and pick off a few more after the first shot.

I've shot as many as four at one time on the pipe line, in the last evening light, with enough light to use a scope.
Shot one under the feeder, herd scattered and stopped at both edges of the woods to look around.
Got another one st the edge, remaining hogs ran the the other side of the pipe line and stopped at the edge of the woods to look around.
They bounced back and forth a few more time until they finally decided to not stop.
Field dressing that many 150 lb. hogs in the dark got old real fast.
Luckily, I wasn't alone on the lease.

:) This above, is exactly why I pretty much shoot my rifles only with a suppressor in place.

I never have fired my LR-308 without the suppressor. Gas is tuned for it. I did get to try a friend's with identical upper and A2 birdcage with my ammo...it was quite unpleasant even with 25-dB muffs and recoiled smartly. I am spoiled.

I have yet to fire my 300BLK AR15 pistol nor my LR-308 without the suppressor either. Like you, the adjustable gas block is setup to account for the suppressor being in place.

Indeed - same here. Built 3x of them, and I still have two stamps on hand :)

I've always wanted a suppressor, but at my age and considering where I live (in the north part of a large metroplex), it seems not to be worth the effort. No real practical reason to have one, except to play with, occasionally.
Also, I've got no one to pass it all on to when I'm gone.
The wife won't want it and will be hard pressed to try to sell all my stuff when I'm gone without the extra hassle of a special lics and tax stamps.
