Looking for advise on primers. I've been using CCI BR2 for large rifle, CCI small rifle, and pistol for a while. They were readily available at the LGS and price wasn't that much different until recently. The gander mountain near me closed, the C word (cabela's) turned to the B word (bass pro) and doesn't stock much just like the mills fleet farm. So.. I'm looking at online sources, powder valley and such. The Remington and Federal seem to be more cost effective compared to the CCI. Up's down's to the different choices? Is a magnum, BR, or standard primer comparable across manufactures?
