Default .45 ACP Primers

I find myself completely out of Large Pistol primers, but I have a good stock of Large Pistol Magnum primers on hand. I use the Magnum primers in my .45 Long Colt Black Powder re-loads.

Can I use the Magnum Primers in the .45 ACP?

If your loads are at max, drop maybe a half grain from the charge.

I wouldn't worry about it, Hodgdon lists 4.0gr as a max load but just using a magnum primer shouldn't increase your pressure much, if any.

If you're worried about it drop down a .5 gr as mentioned above, and work your way up to preference. As long as your gun will fire the magnum primers they should work just fine for you.

Default Mag primers in .45acp.

As stated, just back off of max charge a little+will work fine. Hell, I have been using Small Rifle primers in some small pistol loads for awhile. I found some Rem. 61/2 primers at a deal. They are about the same power as Mag pistol primers, I have been told. Seem to work fine. I'll be glad when pistol primers become available again.

Yeah, been using Magnum CCI primers for years and haven't had any problems with them. I just drop the load on 231 Winchester powder or Bullseye for about 1/2 to 1 grain when I'm reloading 230 lead round nose on .45 ACPs. I haven't used Large pistol primers for years now.

Default lg primers

Just wondering if the lg. pistol primer is still hard to find back Tenn. way? Heading there for a bit, don't want any surprises.
