Feb 27, 2008 · Re: recipe for 308 subsonic loads? Tried my first sub loads today since my can will be here monday. Used 10.5 of Trail Boss with a Remington Premier Accu Point 180 grn bullet.

Jan 25, 2013 · Re: .308 subsonic loads.308 is a tough caliber to take subsonic, especially without fillers. A standard 1:10 twist barrel limits you to 200gr roundnoses at transonic velocities for stability. Trailboss is the least dense powder but I have never been able to get consistent subsonic muzzle velocities with it.

Apr 18, 2024 · First timer messing with subsonic hand loads. Wanting to load a hunting round with maker’s 180 gr Rex bullets. Don’t need to hear .308 vs 300blk argument I have both. Just wanting to mess around with dedicating my Savage bolt action model 10 16” 1/10twist to subs. Only expecting to make shots

Jun 25, 2023 · I have tried 175 SMK in 308 and good accuracy in all twist rates 12, 10 ,9 & 8 barrels 18" 22" 27" & 30".But I used Trailboss powder still have some left ..Trailboss works in everything even in the 50BMG, totally fun.

Re: .308 subsonic I use a 12 twist Rem 308 factory bbl cut to 20" with 147 and 150 subs with great luck. No joy with heavies, other than the 220 Hornady RN. Using an 8 twist 300 BLK, 215 and 230 Bergers were wobbly at 100 yds. These loads were all subsonic, regardless of powder selection. No sideways strikes, but oblong holes in paper.

Jul 15, 2011 · Accuracy will be poorer than with a bolt action, but the main problem is that subsonic shooting at 300 yards subsonic requires the setup time and care for each shot as shooting supersonic with larger calibers at 1000. 308Win. If you have a suppressed 308 win with a 12T it makes sense to have some subsonic loads with moderate weight non-VLD bullets.

Feb 2, 2014 · I have found that using a 147-168 grain FMJ boat tail bullet in a subsonic 308 or 300 blackout/whisper results in poor accuracy. The longer 220 and 240 grain match bullets work very well with a 1-8 twist probably due to the longer …

Aug 11, 2013 · I gave up on accurate loads for the .308 and focused on a .300 blackout which is very accurate with a slow 220gr bullet. I don't think subsonic .308 loads are good for coyote hunting as they lack consistency/accuracy and don't expand. YMMV.

Feb 22, 2007 · BECK loads an amazing subsonic round, Ive tried nearly all of there .308 loads and the 170gr flat point gives me a standard deviation of about 14 out of the box. Everything else Ive tried, including some developed loads I worked on with copper creek have a SD of 25 or more.

Feb 22, 2009 · Re: Heaviest .308 for 1/10" twist subsonic loads? Don't think in terms of chambering,(until past 30-06 case size) think in twist rate, bullet weight, an exit speed. I've ran 30 cal carbine bolt guns with 220 gr bullets, but had a 8 twist barrel, an custom chamber cut. Printed 1/2 moa w/o issue.
