22 CM LG vs Small Primer Pocket Preference?

[Leaf Litter]

I run SRP Lapua brass in my creedmoor/308 family cartridges. Never had a hang fire using CCI 450s and extruded stick powder. If you pack a case full of ball powder you're asking for hang fires in cold temperatures, regardless of LRP vs SRP.

I Shoot a LOT of different Ball Powders, in my .22-250 ( WW 748 / H-380 ) 6 XC and 6.5 Creed ( StaBall 65 ) and Have NEVER had, a "Hang Fire" with, Win lge., CCI 200's or, Fed 210 M Primers.
And IMO, You'd have to have, an extremely EXPENSIVE, B-R Rifle with a "Perfect" Barrel, to tell, the Difference,.. in Accuracy

I'll just put this out there.
I run Federal or Winchester primers, moved away from CCI when availability was zero here.
With my own testing, those .373" case head cases really have no preference for brand, .17, .222 or .223, but the Winchester primers are hotter, and the Magnum Federal SRP is hotter than Winchester.
Moving to .473" cases, Winchester standard primers are hotter than other brands, and the Federal Magnum primer is very hot.
My precision loads using standard SRP primers all prefer the Winchester and all running Magnums prefer the Federal.

Cheers.

SRP, I have lots of them and they work fine, been using them in anything I can from 380acp to 308 for a LOOONG time.
