Ive been spending a lot of time at the bench in the last month. I’ll start with what I’ve done today, and what made me get to this point.
On the left ( 1st 3 rows) is 6.5x55 that I’m testing in a m96 Swedish Mauser with a 16” barrel. 125gr partitions, .020” off the lands, pushed by RL19. With the initial test the best group was 1.27” with the load I started with, so this go around I am going with a few loads under that initial load.
Rows 4,5,and 6 are 280 ackley with Hornady 162gr btsp .020” off the lands, pushed by IMR7828. Initial testing with this combo was very similar to the 6.5. My first load was .875”, so I am trying a couple loads beneath that one, and that first sub moa load.
Rows 7 and 8 are 9.3x62 with 270gr Speer SP, loaded to mag length, pushed by RL15. I had a great load with this combo before, at 57.5gr, these are 58.0 and 58.5gr, just to see what happens.
Rows 9 and 10 are 30-06 with 180gr Sierra SP with .300” of bullet in the case neck, pushed by RL22. Initial testing showed 60.4gr to be the most accurate with a 5shot 1.1” group. I loaded the same 60.4gr load with the first load .005” deeper seating depth, and the second load .010” deeper than the initial. Trying to see if I could tighten the group up a little.
