Title: Large primer vs Small primer
Post by: Blackfoot on September 27, 2014, 07:29:54 AM
Has anyone determined any difference in velocity between loads using large and small primers in .45acp?

I've seen data showing about 25 FPS higher with a large primer.  Not my data, because I won't use the small primer cases.

Good luck, GJ

Hi Gang; I like small primer 45 acp. Brass is cheaper, you do not care if you lose them, people will go out of there way to give them to you.

Mic McPhearson, a good friend of mine, who has forgot more about ballistics than most people will ever know, told me that small primer .45 ACP can be more consistent than large primers. In our game, I do not think it would make a difference.

 ;D bogus, I do know that the small primer is consistent, in stopping my 650 :o. Dusty

Hello Blackfoot.  I've tested that using Green Dot powder and 200 gr RNFP bullets.  Everything the same except the primers.  My data says Garrison Joe is just about right - plus 25 fps for the large primer.  I know some report better consistency with the small primers.  However, my data did not show a significant difference in extreme spread or standard deviation between the two.
