I picked up several boxes of Berger .338 300 grn bullets awhile back. I pulled 10 of them out of one box to see what they weighed. 4 were 299.9, 4 were 300 and the other two were a 1/10 of a grn outside of those two weight groups. The amounts don't seem like a lot for a heavy bullet. However, I'm wondering if there's any kind of weight variance you'd consider unacceptable for long range shooting. The rifle is a 338 Edge.
