Also at the bottom of my list, I'll never buy another WW primer. Piercing with less than max loads, loose fit.Winchester is at the bottom because they had a bunch of defective primers that would pierce at the edge of the cup.
This is my situation. Other component issues are more worthy of study.none affected the accuracy that I am capable of.
I've pretty much settled on CCI as my brand of choice. These days, when I do shoot, it's mostly AR15 / M1 Rifle / M1A, so I use CCI 41's and 34's.
Before their quality went off, I mostly used WW.
I've used RP without issues but (before Covid, anyway) they always cost a few more dollars for no good reason that I could see.
I've used FC, mainly I don't like them due to packaging size.
A few hundred Wolf have come my way, no problems.
I've bought a few bricks of S&B in a previous famine era, never had any problems with them. I think I mostly used their small and large rifle primers.
