Thread: Subsonic load for 308

No you take the suppressor off and test to see the projectiles dont tumble. If they tumble they could hit the suppressor and damage it.
Once they shoot straight and dont tumble, then put suppressor on and carry on

You will have a big elevation difference between subs and supers. My supers are sighted dead on at 100yds. I need 6MOA elevation to get subs to zero at 25yds.

4.5 MOA difference for me between supers at 200m and subs at 50m

Yep. Same here. Zero for 168gr at 100, 8moa for subs at 25

I'm hoping for mine to be a dedicated subsonic rifle.
And supersonic as a secondary option

I will have a 260AI and a 6.5 creedmore for any hunting requiring higher velocities

Did you see this? a series of 3 vids...interesting. (hope it's the right one.)

in the second video, that sweet dog is right up in the stinging nettle. its supposed to be deadly to dogs from what I ready?

Has anyone tried using 2205 for subsonic loads with the 208gr projectiles in 308.
Trail boss didnt work so I might try 2205 cause it worked in the 300blkout

I've tried 2205 in 308 with 220gr RN's, and in 7.62x39 with 180gr RN's (bad bullet choice btw).

It works reasonably well. I got more consistent velocities than with trail boss. On the other hand, it's a lot slower burning than train boss - pressure is so low that cases don't seal the chamber, and there's more pressure at the muzzle meaning it's a fair bit louder.

Has anyone tried the Winchester super x subsonic loads?

Nah I don’t reload - maybe later I will, so the factory rounds appeal, if they work - I use a 300 BLK at the moment with supers and subs

what is the maximum distance a 308 sub load would be good for?

Depends on the sub projectile. I'm pretty sure one of the guys in here has shot deer at a couple of hundred yards with subs using the lehigh projectile. The lead HP ones, about 75yds would be the limit.

I limit myself to 50m with the cast 150g and trail boss,look at it like bow hunting,unless you can brain or spine shoot them be prepared to do some tracking.
