I've used enough pistol primers at least have an opinion on them...maybe 150-200k.
I've used CCI, Rem, Win, Federal, and Magtech. I've been unable to get Tula/Wolf here in town, so I'll probably have to send somewhere for enough to justify the hazmat.
I've never had a problem with any, except when I didn't seat them deep enough. That's what I get for being in a hurry, and not paying attention.
I've never been able to figure why one would lighten the hammer-strike, then again, I've never competed in bullseye.
I have competed in trap, IDPA, and sillywet, both pistol and rifle. Pistol was always Hunter, and the rifle was 5-6 different types, including MilSurp.
I have preferences, but they are mostly personal, rather than performance, choices.
Much of my shooting has been over the chronograph, so that I could quantify the differences between brand and heat-range.
There doesn't seem to be a lot of difference, but with SOME powders, there is a bit!
Have fun,
Gene
