.45 Colt - crimping with no cannelure?

If you wanted to load .45 ACP jacketed bullets in .45 Colt and the bullets don't have a cannelure, is it normal to seat the bullet deep enough that you can roll crimp the case on the ogive? I know CH4D makes a cannelure tool but I don't have one yet. I don't want my bullets walking out of the cases and locking up my revolver, done it and it's no fun.

You could do that. I just load to the O.A.L. I want and use a Taper Crimp. A .45 ACP seater will work if you have one, or you could buy a dedicated taper crimp die for .45 Colt like this Lee (http://www.midwayusa.com/viewProduct/?productNumber=641748). Redding makes a nice one as well, but Midway does not seem to carry it any longer.

Neck tension is especially critical to holding bullets put from "walking out" under recoil when not using a roll crimp. The taper crimp will help, but can not make up for poor neck tension. Good neck tension is needed for a good burn regardless of the type crimp.

Most .45acp bullets aren't heavy enough to walk out of the case when fired in your typically heavy .45Colt revolver at normal .45Colt velocity. Neck tension alone should hold them in place unless you've got an old set of dies that is sizing for 0.454" bullets.

"is it normal to seat the bullet deep enough that you can roll crimp the case on the ogive?"

You don't want to roll crimp any rimless autoloader handgun cartridge at all, simply removing any mouth flair with a taper crimper is all that's useful.

I bought my cannelure cutter from Corbin ($139.00) to use on .223 bullets. In my opinion it's way too expensive for what it is. For .45 LC I'll agree with the previous poster who suggested the taper crimp die from the .45 ACP. As long as the loads are reasonable it should work fine.

I ran a post on a very similar subject about two weeks ago. There were some interesting comments. My personal experience was that I could crimp the 45 ACP bullets and make them shoot well, but that it probably wasn't worth the effort -- I'll stick to cannelured 45 LC bullets.

+1 on the comments regarding case neck tension being the key factor in bullet retention. When loading .45 Colt, I have dealt with the lack of a cannelure (which is typically associated with plated bullets) by backing off the normal roll crimp until it's just enough to straighten the case back against the bullet, or maybe slightly more, making a very light indentation ring on the bullet. Manufacturer's like Berry's and Rainier say that mild crimping is ok, but the bullet plating is quite thin (too thin for a cannelure, that's why it's not there) and you don't want to tear it with the crimp. I then measure the reloaded cartridge in a .45 Colt case gauge to make sure the case mouth is within standard specifications.

Shooting the rounds assembled as described have produced no suprises. Accuracy of these plated bullets in my .45 Colt revolvers (Anaconda, 25-5, Blackhawk) is so-so. I'm not a big fan of these plated bullets, but they are priced right if you feel like taking a break from scraping lead out of your guns.
