A quick question about that ring on the brass.

[sublimaze41]

I was cranking out some rounds last night and I got to thinking. Just what is the purpose of that dotted ring 1/2 that way down on some brass cases?

 

[alucard0822]

It is a base crimp. Designed to prevent setback of the bullet into the case from recoil. Don't worry about it, I have a bunch of 44mag with it that are probably on the 10th load, and look fine.

 

[strat81]

It's for the factory crimp. Worry not. I've loaded hundreds of 9mm FC cases that have it with no ill effects.

 

[sublimaze41]

Is it safe to say it poses no use for reloaders?

 

[Linear Thinker]

It is indeed safe to say so. You can get a cannelure tool from Corbin that would duplicate the ring... I wouldn't bother.

I use the Corbin Cannelure tool to cannelure Bullets made from swaged .22 rimfire shells and lead rod. Works well for that. Never had setback issues with my loads but I toss out the crimped cases as I do not want a separation and that ring is a weak point.

SilentArmy...Next time you have a bunch of cannelured cases to toss out put my address on them first...I have no problem reloading them...
