Well I finally got a chance to do some barrel break in and load development.
I decided to go in a different route with powder. I found 2lbs of Rel 17 that I had originally picked up for my 325wsm (but sold the
so I figured I'd give it a try.
I tried both 54 and 55grs with the 168gr Bergers. 54gr shot really well but velocity averaged 2749 and was all over the place. The 55gr load got sticky bolt lift and didn't shoot as good. I think part of my problem is being stuck with loading to magazine length if I want a repeater.
I then tried 55 and 56 grains with the 160 Nosler Accubonds. 55grs shot ok but the 56 grain load was unbelievable. After the cold bore which was immediately after cleaning, I put the the other 4 in about .65 moa with an average velocity of 2915 fps and ES of 12fps! No signs of pressure. Should be a lights out load for Blacktails this year!
