Primers info

What is the difference between a Large pistol primer and a "magnum" large pistol primer ? Will the magnum work for bullseye loads ?

Magnum primers have a hotter flame (more energy) required to efficiently ignite some of the slower burning powders used in magnum pistols.  They certainly are not needed for our light bullseye loads but will work ok.  If for some reason you are loading maximum powder loads, don't switch to a magnum primer without backing off on amount of powder first.  I have used magnum primers when no others were available and they were ok.

Thank you,
I just got 2,000 with a purchase of some other items, I wasn't quite sure what to do with them.

I also have 10,000 TulAmmo large standard pistol primers, are these any good ? I have been using Winchester and CCI primers with good success.

I've used the Tulammo primers and they all went bang.  Did not really see any difference between them and Winchester or CCI primers.  I did have a problem with some really old ones.  The anvil on a couple were a little high and they hung up in my Star press primer slide, since the tolerances are really close.

Great, Thanks for the input.

Never tried mag primers in a .45, but I ended up with 10k of the Tulammo large pistol primers back when primers were hard to find. I started using them a couple months back in my practice ammo only to find that they really work well in my Hornady LNL. Even better than Winchester. Ammo seems to be just as good and every one of the first 1k went bang. I would buy them again.

About all I ever saw was some loss of accuracy and a slight increase in velocity and increase in std dev.
