45 acp crimp
Can you tell me a website or a book that I can see a picture
of a correctly crimped compared to badly crimped 45 acp.
I don`t have a bullet puller yet and I don`t want to go
experimenting with my reloads without being able take my
bullets apart and start over again. For now I am crimping at
the min suggested setting and there is a very slight difference
that I can see in crimped and not crimped, and I am wondering if
I am being too carefull.
Thanks very much for any help.

Do you still have a (shudder) factory round?
If not; the edge of the crimp should be shiny where it meets the bullet, and actually "feel" like it's a smooth transition from brass to bullet.
The ideal crimp for an auto round should be into a cannelure-that's why they make 'em.
I use a lighted magnifier to inspect the crimp until I get it to where I like it. Go slow, or you'll get a bulge behind the bullet.
Uniform case length is pretty critical if you don't want to keep adjusting up & down for each round.
Just make sure they're pretty much the same overall length when they're done in the seating die, and then work your way down slowly with the seating stem removed until you get a nice crimp-the idea is to crimp enough to hold the bullet during recoil without working the brass into the jacket too far.
If you know it all; you must have been listening.WEAR EAR PROTECTION!0 -
The easy way to crimp a 45. ACP, is use a 7 by 57 mauser bullet seating die. Just run the 45. up in the die, till you come up with a bullet, and case, that blend very smoothly, and you have it.
All you have to do is make a stop out of a piece of threaded stock, and you have it. I have crimped many thousands of 45. this way, and they shoot great. I use a RCBS die.
These rounds load great in chamber, with the correct head space.

Get a taper crimp die. makes the best looking 45 ammo. 0 -
I second the taper crimp die, I shoot cast frequently and taper crimp the he!! out of them and make sure they drop in the barrel, and rarely have a jam. 0 -

the only time you see a real / noticable differance is at long ranges (over 50 yds). having a proper military style GI crimp in the correct location seems to increase accuracy, and decrease group size. we first noticed this when reloading for a customer who bought one of those drop-in carbine conversion kits from BLUE PRESS, and SPORTSMANS GUIDE. at 100 yds, the crimped ammo shot better groups by an order of magnitude. i have no idea why this is the case.
we also have a customer with a real, authentic british enfield bolt action rifle that was converted to fire .45 ACP from a stick mag. he also has noticed the differance in accuracy.
if you are only shooting a 1911 style pistol at ranges under 50 yds, i do not think it makes much of a differance. best regards, mike.
