I pretty much use Winchester primers any more tho I still have some CCI, Federal and a bunch of old,old Peters (Rem) primers in stock. I rarely, if ever, use maximum load data so I don't worry to much about switching them around UNLESS I substitute a magnum primer for a standard primer, then I back off a bit and work up again.

I've never noticed any diffrence in performance between the diffrent rifle and pistol primers out there with one exception, I have a 30-30 Contender that seems to prefer Federal primers over the rest.
