It's not something that ever really concerned me but recently I have been trying to shoot some groups from the bench with my 45-70 (as I mentioned in another thread).
I shot a reasonable group (2.5" @100 yds.) with store bought boolits.
The next week I shot a horrible group (6+" @ 100 yds.) with my own gas check boolits.
Upon weighing them after the fact, I am finding my boolits weigh from 395 to 405 gr. That would seem to indicate the problem but, the store bought boolits that are supposed to be 480 gr. weigh in at 500 to 510+ gr. and shoot well enough.
I realize it can't hurt to have them all the same, but is it normal to have to weigh each individual boolit to get any kind of accuracy? And what about the bought boolits, they are inconsistant as far as weight and shoot OK?
MOA would be great but if I can just cast em and shoot em for 2.5" I would be happy.
Thanks,
John
