[QUOTE="cb4128, post: 1634272, member: 80069"] Am at a cross roads in my 338 lapua reloading process - I worked up to max in .5gr increments at 100 yards and had 2 good loads - 1 was at 89.5gr (about 3/4" in a triangle) and 1 at 90.5gr (.4 - 2 in 1 hole and 1 just lower). So, I revisited the 90.5gr and adjusted my seating depth; but with my magnetospeed attached to get velocity spreads. My groups were terrible, but I had 1 really good velocity spread at .090" off the lands - SD-3, ES-7 (2,749 fps avg) *First thought is to load up that same 90.5gr load at .015" off and .090" off and see which one groups better (without the magneto attached, as it definitely affected my groups on this rifle) **Does anyone have any suggestions that I should try? Current load recipe: Lapua brass Federal 215m primer 300gr Berger Hybrid 90.5gr of H1000 I also have Retumbo to try, but wanted to continue down this path for now as it shows promise and I know several guys have had good luck with the H1000 powder with these components.
