Re: Somebody needs to tell a story or have some questions he

Most modern 45 Colt FMJ bullets are .451 dia, same as 45acp and .452 for lead bullets. Hornady makes their 45 Colt FMJ bullets with a .452 dia but their 45acp is .451. I guess this is why they have a 451 and 452 expander. I am not sure why they make the Colt bullets .001 larger than others but they also make 44spl - 44mag FMJ bullets to a .430 dia instead of .429. My guess is just to be different.

Since most belling dies are adjustable I think the .001 difference is a mute point anyway. I have never used or seen a LnL setup so I am making assumptions the expander is just a powder die that also bells the mouth to ease seating.
