Loads for 16" LR308 150grn. with TAC

[Rifleloon]

I've loaded up some of these with 41.7 grains and was able to check function, but I haven't chronoed or accuracy checked yet. I'm using rem 9 1/2 primers and winchester brass. They funtion fine and bolt locked after last round, but I'd like to get an idea if I can go hotter without getting close to max.

Any info appreciated. (other than weather reports)  ;)  ;D

Hit this for the recommended load data - you seeing any pressure signs with your load now?  What's the max load that they suggest for that projectile?

No signs of over pressure. The listed max charge is 46.0

Ramshot Data is with 24" bbl. Probably a bolt gun or test bbl.

I emailed Ramshot several months ago specifically about 150gr FMJ load data.  Here is the load data they provided to me:

150gr Hornady FMJ  42.4gr start  2,715 fps 47.1gr max 2,957fps

tested with 24" barrel  calculate a -8.3% velocity drop with a 16" barrel

OK, I finally got out with my "Beta Master" chronograph and

what I'm getting is 2461 FPS average of 10 shots 15 feet from the muzzle.

Although I don't shoot for accuracy when I chrono and was getting a scope zeroed before that, I did get a couple of one hole with two shots. This was only at 50 yards. I know the .308 is one of the "inherntly accurate" rounds so I doubt if I'll lose any thing if I bump it up a little. I think I'll try some with 43 grains of TAC and see what that does. I don't feel the need to max out the speed , but DO want to get the full potential of the 150s.

Any thoughts?

Federal XM80C ammo from my 16" BBL. --  2676 fps. avg.

Federal XM80C ammo from my 20" BBL. --  2781 fps. avg.

Of course this is with a 149 gr. bullet , so you have some room to play with the fps..
