...I also read an article in Handloader about the small vs large primed 45 ACP ammo. No difference to speak of, less than 100 fps lower velocities with small primers...

Then Federal must load them differently, since the fps and other load data on the boxes were identical.

I guess I'll have to search for that other thread on this forum that deals with this issue.

Thanks for the input guys!
