I load both identically and haven't noticed a single difference.
...AND you could use small pistol magnum primers and gain 20 FPS as well.
For me and my 45's, some 12-14 of them if I remember right!I was going through my brass, and noticed I am running about even between small and large primer casings. I Gurgled, however, not much info out there.
So, is there anything special I need to know loading SPP casings with LPP data, or just rock on with a different primer?
Enlarging the flash holes sounds like it could be dangerous, no?If these cases were all I had, I'd load it to spec and shoot 'em. Large primer or small, they'll both yield similar results with published load data available.
Everything I load is built up from range brass and my big thing while reloading is consistency of components within each batch I reload. So each time I reload I separate my brass by brand and toss anything that looks questionable. I can load mixed brass and get it to function correctly, but the end result will be mixed also. I enjoy shooting for distance with my revolvers, and when I reach out to 200yds., inconsistent(mixed) reloads always let me down accuracy wise.
This pic shows one Blazer SP primer pocket, a LP CCI and two nickle plated LP Federals. Each one has a different sized flash hole. Even when loaded the same, I doubt these four rounds could produce a bug hole at 10 yds.

I was told once that it helps the powder burn cleaner, but I toss all brass where a previous reloader has enlarged flash holes.
