I'm in the early stages of load development with a Ruger American Predator (18") in 308. I'm getting 2965 average with Benchmark a little below pressure signs. I still need to test a few more variables, but it's at about .8 moa right now. One thing I think/hope will help is adding a little more neck tension. I'm using the Lee neck collets and they comes with .003, and the bullet seats (and pulls) really easily. I've ordered .004 and .005 to test out. Then I need to test seating depth, then crimp, the small powder charge variances. Unless I get to 1/2 moa, then I'm calling it good so I can move on to the next rifle load development.
