45 Long Colt crimping

[Boogerman59]

Hi Folks,
I reload, and just got a Roger Blackhawk 45 LC. I picked up some Magtech Cowboy action rounds while I wait for my dies to come in. Notice a secondary crimp at, what appears to be the lead bullet. Can anyone tell me what kind of dies do this?

That crimp is at the base of the bullet to prevent setback. I don't know how much of a problem bullet setback can be with low velocity stuff like cowboy action loads, but that's what it's for.

I don't know of a die, or any other tool for that matter, that a reloader can buy that will replicate that.

First, where the heck did you find 45LC ammo?

Second, that's a factory thing as mentioned above. I can't speak to what's available to reloaders in terms of tools but I can say there are tools out there to put a cannelure on bullets

 

[Charlie98]

Is that a factory cartridge? It doesn't even look like it's crimped...

 

[Ru4real]

Come on folks! Light reflection is a dead giveaway. Roll crimp. Standard die.

 

[Boogerman59]

The ammo is Magtech Cowboy Action 45LC, purchased from Cabella's a couple of years ago. I just got it out and was curious about the crimp style being like a crimp groove on the Hornady FXT.

That does NOT look like MagTech Commercial

(either of them)

In fact it looks like someone's handload, and already set back into the case.

See?!?! That's what I thought. In fact, the case mouth looks like it's still flared OUT.

Yup... and different bullet too. Almost looks like it might have a
SWC shoulder below the nose, and seated below case mouth.

Sumpin' wrong here....

I took a few more pics of the round for you guys to look at. Looks like it would trash the case after firing with those fine lines pressed into the case.

 

[DocRock]

That’s FEDERAL brass, not Magtech (the headlamp for which is CBC) and those are Keithesque SWCbullets. So, those are pretty likely to be reloads.

The case cannelure has no impact on reloadability whatsoever.

 

[Boogerman59]

Damit, My son purchased a Ruger Revolver back in 2014 along with the ammo, as a Birthday gift. He purchased it from a Gun Shop in Hurst Texas, guess they reboxed the ammo in a Magtech box. 50 rounds of what?????
I have not fired any of this ammo, it has just set in the closet. Do any of you think this stuff is ok to fire? I have since started reloading, that's how this thread started, I was interested in the jump crimp that was used to make the indentions in the case.

As @DocRock says, federal case. It's been mentioned before that often that secondary ring isn't always to prevent setback but to differentiate loading. It isn't important and the cases are totally fine to reload.

Looks like that to me too.

I've shot a lot of magtech cowboy 45 colt, it's not that.

Thanks for the info DocRock. Just another reason to load/reload your own ammo.

 

[Obturation]

I wouldn't fire them, somethings fishy. Never fire cartridges that you don't know the origin of it that something seems off.

Thank You To Obturation for the info. differentiate loading?????

 

[Boogerman59]

Thanks for all the help folks, guess I will go pull some lead and reload these.

Those case cannelures will size out, eventually. I have .45ACP and .45 Colt brass with those... it's a non-issue.

I call those kinds of rounds Mystery Meat Reloads. They are a no-go in my firearms.

differentiate loading?????

The mid-case cannelure shows where the base of the bullet is, very often you can tell how big the bullet is (what weight, for example) by where the base ends.

 

[Obturation]

differentiate loading

There was a time where black powder loading were in certain cases and smokeless would get an extra impressed ring on the case for an easy visual aid. Not likely the case on these but you never know because the cartridge is such an old one. I could be mistaken though and forgive me if I'm wrong but I believe it was @Driftwood Johnson that was discussing this recently . either way, the extra groove in the case won't matter, can't be reproduced and will finish after firing and sizing a few times

The cannalure was originally meant to prevent bullet setback. Today with proper neck tension and appropriate bullets and crimp (bullets with crimp groove or cannalure and roll crimping) these cannalures are not necessary. Reload as usual and ignore the cannalure. Also sometimes used as identification marks.

I'm not familiar with Magtech Cowboy loads but I don't like the looks of how deeply seated the bullet is and crimped over the shoulder (?)...

 

[MEHavey]

The brass is/and will be just fine for reloading.,
No problemmo.
Hie thee to an impact hammer bullet puller though.

Good eye, at least you didn’t take the box or the rounds at face value. If something looks odd it usually is.

I wouldn’t shoot those in my .45 Colts either. Pull the bullets and start over .

Stay safe.
