Mostly, but not quite. You might want to sneak up on max loads originally developed with one type of primers when switching the load to another type - small or large, standard or magnum, etc. You'll want to sneak up on the maximum loads in your loading manual, anyway. Someone else's max might be beyond yours.txn1911 wrote: ... are they interchangable, looks like no.
I only use standard pistol primers in .45 ACP. My loads have not proven overly sensitive to particular brands of primers. However, some priming tools are apparently brand-sensitive.txn1911 wrote:... what are some general recomendations for powder and primers for 45 ACP for full size 1911?
I ended up with 750 pcs of small primer .45 ACP cases, out of about 3750 pcs total. Seemed to run about 20%. At 750 pcs, that is enough to make it worthwhile. Ended up selling to someone who wanted to simplify their calibers and load small primer in all of them.mr surveyor wrote:I cull all the small primer pocket .45 acp brass.... not enough of them around here yet to worry about keeping them
Personally, I was not a fan of Unique or AA #7. There are so many modern powders that meter reliably like metering water, I see no point in using a poor metering powder like Unique.mr surveyor wrote:I use standard large pistol primers and mostly Unique and AA#7. If they cycle well in my old 4# Kimber with a heavy mainspring, they'll work in most any .45 acp pistol

As far as AA #7, it is almost the opposite end of the spectrum. The powder is so fine is sifts down everywhere. Which is fine, I didn't really care about the mess. I didn't continue using it because I got smaller groups and less recoil from Universal Clays, W231, Ramshot True Blue, Bullseye, and Clays.

Standard loading practice for just about any caliber is to start the powder charge about 10% under the maximum charge, and gradually work up from there, looking for the typical signs of pressure.airboss wrote:Hmm. So is it OK to use the identical powder charge in either (large primer or small primer) case, or charge one slightly more than an other?
Lately, small-primered .45 brass is up to about 25% of range pickup brass. It started with NT ammo, but has now spread since it is a cost savings to the ammo companies.AndyC wrote:.... - much to the annoyance of reloaders, who now have to cull out these small-primered cases manually.
