.45 Colt Question

[.460Fan]

I always get kinna curious when I see something I haven't seen before.

I bought some .45 Colt Super X Lead rounds for my 460V I noticed the casing looked like it was belted about 2cm up from the rim of the casing.

Any reason for that?

You mean a ring, don't you? Some cartridges have that as a stop to keep the bullet from going too far into the case.

Here is a picture of a 200 grain Magtech, 225 grain Remington and a 255 grain Winchester.

Yup that would be it. Thunder that would be the exact same round.

I guess it would be a ring of sorts. Makes sense. I thought that might be the general idea but it never hurts to ask.

My .460 rounds from Hornady doesn't feature that and neither do my .40 S&Ws or .45 ACPs

Once I figured out it was solid lead I changed out the muzzle comp for it. But hey cheap practice ammo is cheap practice ammo.

It was humorous to explain to the dude at the counter that .45 Colt and .45 Long Colt is the exact same round though.

Does that ring get in the way when you reload? For instance if I want to put a 255 grain bullet into the fired case of the Magtec 200 grain load?

It likely would. Looking at both of them, their math is done by case length and bullet length so that it ensures proper gas buildup and burn for pressure purposes. Nothing says "****" like powder snuffed out by lack of oxygen. lol

You'd have to support the case walls from the outside and have a device repress the case walls from the inside so it's done evenly and will retain structural and engineering integrity.

After that you'll likely want to repress another ring 2 cm above the rim. Or slowly and carefully insert the round by some kind of hand press.

That's my guess as I am not a reloader. If it's made by man it can be altered, remade, made better, made worse, done, redone, or undone as well as broken or fixed.

I'm looking forward to the day I can practice reloading though. But I don't have the room for the equipment.

The ring is called a cannelure. It will have no effect when reloading a fired case. It won't matter which bullet you use, you can ignore the 'ring.'

Glad to know. And that's why it's a guess. lol

Thanks for setting the record straight on that.

It usually doesn't make a difference. However, I once had some brass with a cannelure that I seated longer bullets in. The cannelure was pushed out, slightly increasing the diameter of the case there and making chambering difficult. The rounds still functioned fine but in general I avoid cases with a cannelure if I have other brass available to load.

Doesn't gun powder have it's own oxygen to burn? Won't it burn even in a vacuum?

A Lee Factory Crimp Die should solve that problem. In order for the cartridge to get in and out of the die, it has to pass through a hole which is sized in such a way that any cartridge that goes in and out of the die will fit any SAAMI spec. chamber of the same caliber.

Yes. It needs no additional oxygen to burn.

After a firing or two, that "ring" will be pretty much gone. At least, it will not be nearly as pronounced as it is in the factory load. The cases work well for reloading. I've used 1000s of them through the years.
