This. There are few better ways to get in trouble than by switching components when you're already at top-end pressures. Back off and work back up until you either see the same velocity as before or you start to see pressure signs.

Thanks for all the advice. I'm going to start buying them up, when I can find them.
Pre Covid/BLM I shot only Federal for USPSA. Of late I'll shoot anything. Testing loads I have found the Federals to be consistently hotter than Winchester and CCI standard small pistol. The Winchester small magnums were no different than standard Winchester and CCI. The CCI small pistol magnums were close to the Federals but not quite.
I don't download for any of this, but I'm shooting puny USPSA match ammo. If you're loading to high pressures/velocities it might be good to back down a bit.
If you are the type to sort your cases by headstamp, then by weight, and then trim them all to length, you might see a difference.
Case capacity matters more than primers.
CCI, Winchester, Federal, Remington and S&B all produce ammo with the same average power factor me (IPSC). But, Ginex and Dominion need a 0.3gr powder increase with Titegroup to get the same PF.
Interesting I just got 5k of the ginex primers.
I’ll have to chrono them before I get too carried away with reloading this winter.
I’m curious about what caliber and bullet you needed .3gr more titegroup?
I shoot boatloads of Campro 124gr 9x19. 4.1gr of Titegroup gets me about 1080fps out of my Glocks
No experience with Rem primers but even Russian primers work just fine. Used the last of mine last year. If they were garbage I would have chucked those a long time ago.
No primer shortage here at my house..
I shoot 147gr CamPro. I don't use ginex for matches, but do for practice. To make the same power factor I'm shooting 3.6gr of Titegroup instead of 3.3gr
