its been my experience that the FEDERAL AND WINCHESTER
primers, on average are slightly more consistent than the CCI and ALCAN primers but all four of those those brands are well ahead of the REMINGTONS, now what I mean by that is that IVE generally gotten better groups and less deviation in velocities, with those brands in that order, but they all work, and age, care in reloading and the strength of the striker or firing pin and temperatures plus the powders used do effect the results
FOR PISTOLS
the primer used depends on the powder, with medium burn rates like anything from herco- blue dot
I have never seen any difference in the primers, slower powders like H110 -296 usually get better accuracy with mag primers
CCI, and WINCHESTER MAG PISTOL PRIMERS PREFERRED
I use a good deal of herco-&- blue dot in most pistol loads even some hunting loads but I generally don,t load to max pressures even with the slower H110 but I don,t see where using mag primers on everything would hurt, they generally don,t cost much more
FOR RIFLES I only use WINCHESTER OR FEDERAL MAG RIFLE PRIMERS
