I worked up in 1 grain increments. I started at 72 grains, loaded one round up at 73, 74, 75, 76, 77, 78. 74-76 all shot into almost one hole at 100 yds. 77 grains showed a little pressure, and I didn't shoot 78. Kirby told me he likes to load till he sees pressure then back off two grains and that's usually a pretty good load. So, I backed off to 75 and loaded six rounds. It shot well at 500 and at 1000. So I called it good. However, That was with virgin brass. Once my brass was once fired, I noticed my groups started hitting a little low. I increased my load to 76 grains and groups went right back where they were. Maybe I got lucky. But, I'm going to do the same thing with my new 300 as soon as it's finished.
I'm worried about the 215 hybrid. The box says not for hunting. I mostly hunt large whitetails and shots can be close in the timber stands. Should I just try another bullet for this application? I was really wanting to stick to a single load for all my hunting from deer to elk.
