cinteal,
Yes ,the bullet must contact both sides of the barrel, however, not one side at a time!

Don't worry, unless you are shooting seriously hard bullets, they'll slug up and fill the bore.
I never measured my crimp before in all those years (they just worked), but all the "I crimp to .XXX" got me wondering.
My mix of range brass is all kinds of different lengths, all different kinds of "springy", and all different wall thicknesses. I don't even bother to sort by headstamp. (I do for revolver brass)
I measured some and they ranged from .469 to .472. Shoot like a dream. Out shoot me easily most days. Some days I still have it though.
OAL; COL; Headstamp; Bullet design, weight, diameter, consistancy; and CRIMP are all variables used in making the bread & butter load for a particular gun. I posted my loads that work in all my 1911s . . . that's 13 Kimbers (stock to custom), 2 Wilsons (CQB 5" Bull barrel with extras and a CQB Elite), and a Dan Wesson PointMan.
If anyone is interested, I put the calipers to the Green Dot 230 FMJ load I posted. It's crimped at .471.
My 2 recipes fill up the barrel quite nicely as, off of sandbags, at 25 yds, they both shoot 1.4" 5 shot groups out of the CQB Elite AND Kimber Super Match (5" barrels). I can't tell a big difference when using the Bullseye load in 4" and 3" barrels. The Green Dot load is for 5".

It varies. I get 2-3 loads from Amerc, usually. I bet I've loaded some Federals more than 10 times. Some in between. I don't really keep track in pistol calibers. There is nothing wrong with buying once fired, even if it's been shot from a Glock. We're talking relatively low pressures in a 45 ACP. Once fired is typically going to be factory loads, and their not going to exceed SAAMI specs. Or, buy factory and make your own once fired brass.
You will want to stick with fast powders in the 4" barrel . . . something with which you can maximize burn rate. Bullseye (cheap & proven, but dirty), Red Dot, AA#2. My load for 230 FMJ in my Pro guns is
Mixed Brass
4.9 gr Bullseye
OAL= 1.250"
This shoots well for me with no problems. Point of impact is a couple inches high at 25 yrds in my Pro CDP, Pro Raptor, Pro Tactical, and Pro SIS.
In small capacity cases, you may not have but 1 - 1.5 grains between recommended starting loads and max loads, sometimes less with fast burning powders. Some of these guys have recommended .5 grain increments. With .5 you've used up your range of loads with 2 sets. Small cap cases need smaller increments. I would suggest .1 grain increments, but definately no more than .2 grain. Initially, what I would look for in a good load is point of impact for the ProCarry's fixed sights. It's a pistol, short barreled at that. Loading for the smallest group can be done, but there's not going to be huge differences in 45ACP groups. If it goes bang and hits what you're aiming at . . . you've arrived.
I suggest that you work for a POI of 1-2" high from your POA at 25 yds. You'll be closer to POA at shorter distances and closer to POA at distances out to 50 yds.

In the interest of science, I measured some old GI issue .45 ACP ammo from my stash this morning.
WWC 64 National Match 230 ball = .471" crimp.
RA 65 National Match 230 ball = .4695" crimp.
RA 68 230 GI 230 ball = .469" to .471" crimp in the same box.
AOL ranges from 1.266" to 1.271" for 230 grain GI ball.
In pulling the bullets from both National Match loads, there is a tiny shiny ring around the bullet at the case mouth where it didn't oxidize, but no depression in the jacket whatsoever, at all.

cool. I wouldn't think it would need it on copper. I don't really know that it needs much of a bullet depressing crimp on lead.
Still, was the match ammo crimped consistantly through the whole box? Please measure and report back
Just kidding. I am always impressed by the information in your posts and the resources to which you go to get it . . . especially when it supports what I do . . . and even when it doesn't.

I did measure enough to tell the Match ammo was very consistent throughout the two boxes.
The Ball ammo, not so much.

Ya know, when I was hitting the button to post my smartass comment, I said to myself, "He probably has already measured that stuff for consistency."
I'm at home sick today (and for the weekend ) I think I'll go measure some newer stuff.
