Got a question about Magnum vs normal primers for BP cartridge (pistol and BPCR).
I've heard several opinions and don't know what to believe.
Magnum primers result in a cleaner burn. I remember reading that 10-15 years ago, magnum primers were popular in BP cartridge reloading.
Magnum primers result in slightly higher muzzle velocity, but leave harder, baked on fouling (which is clearly a problem). I seem to remember a post referencing old reloading data which implied that hotter primers left baked on fouling and were developed in response to smokeless powder.

I've used standard power caps and primers in frontstuffers, single shot pistols, revolvers and BP cartridges for over 30 years at rendezvous', CAS matches and informal shooting matches. While I don't shoot long range BPCR or silhouettematches, I've never seen the need for magnum caps/primers when using real blackpowder.
Now, using that fake stuff.....................
