I'm fairly new to loading precision LR ammo. I just purchased a Rem260 here off the hide that came with load data. The load calls for CCI BR2 primers. I was just curious how much of a difference using a standard large rifle primer would cause.
I use BR2 for my 308win and 6.5 Creedmoor, as I was able to get a good price in bulk. The BR2 are more consistent, but you probably won't notice a significant difference unless you are shooting pass 300 yards.
