I shot the .270 again today loaded with Magnum and MRP with two diferent seating lengths: one with a .08" jump and the other with a .015".
MRP loads shot tighter, and quite well, around 0.6-0.7 moas for four shot groups, regardless the seating depth. Impact varied a little but group sizes were identical.
Speed was 2,885 fps and my next loads will be with 0.8gr more powder with the hope that n o accuracy is lost.
