I have a question regarding my reloads. I am currently loading for my 308. I am using 39.7 grains of 4064, Remington 9 & 1/2 primers, and 168 SMKs out of a thirty inch barrel.
I am getting from 2,499 to 2,534 fps. The best group so far is .295" center to center.
There is still room left in the case for a few more grains as I was able to dump 42.5 grains into the RA61 brass I'm using. The group's did shrink a little bit, with one at .462" with this charge weight. Velocity is about 2,840 fps with this charge.
My question is, should I load a higher charge than the 42.5 grains and see if they tighten up in order to shoot a higher velocity?
Right now I've only access to a 500 yard range.
It seems this velocity is really low for a 308 and 168 grain bullets.
I only use the rifle for ringing steel right now.
Thanks for any advice.
