I've used it with 50 and 55 grain bullets in .223 and 5.56. Also good in .444 Marlin, .45-70, and .458 SOCOM. SOCOM with heavier bullets, .45-70 with lighter ones.
I burned a lot of it in my misspent youth, killing crows with a .222. It also works well with lighter bullets in the .358 Winchester.
Good powder.
