The guy I brought his up to said he was just as accurate with big, hard kicking calibers as small ones. The only way he can test that is to get a good estimate of his actual cone of fire with each gun. If he has a gun that has a hot bore issue, that’s a whole different problem. If spacing his 10-30 round group over hours makes him feel better about it or feel more accurate, great. The question is really what is the effect of recoil on his shooting.Lots of ways to skin this cat if putting 30 through a hunting rifle in a single sitting isn’t of interest. I like a cold bore/cold shooter group over time for hunting rifles. 3x5 Index card with a target dot in the middle of it. Tack it to the target backer, it’s always the first (and only the first) shot on a range trip. Sometimes that’s the only shot from that rifle for the trip. All shots count.
Doesn’t really work if you can only do it a couple times a year, but if you shoot frequently it doesn’t take long to see what your rifle (and you) is doing on that shot that matters most.
