Re: Loads for 168 gr berger out of 280 ai
nmsheephunter, I just recently had the same issues. Tried h4831sc, h1000 and imr 7828- all gave good groups(imr 7828 gave excellent accuracy) but muzzle vel. below 2800fps for all 3 powders. Then I tried rl 17- working up to 56.5 gr-I got 2940. I settled on 55gr @2900 then played with seating depth and I now have a great load. In the begining all testing was with the VLD's touching the lands but after some more testing I'm at .070 off. I have a 24" barrell.
