•••CASES with and without cannelure •••?

[the Black Spot]

Did a little search, couldn't find what i was after.
I have little time for experimentation, and was wondering if a name brand 45 colt case that has both non-cannelured and cannelured cases, will there be an accuracy difference between the cases(all else equal)? (Or am i "much ado about nothing")
Thanks!

Are you talking about a ring rolled into the case further back from the mouth?

 

[the Black Spot]

Yes

 

[Kaldor]

Some manufacturers put those on the brass to prevent bullet set back. No worries, treat those cases the same as the others. Load em and shoot em.

Those rings/indentations generally get "ironed out" on the inside of the cases in 1 or 2 firings. Nothing to worry about or do anything about.

I don't care about that ring. I reload them with or without. All the same.

Thanks!!

No difference at all. Just load them both the same.

Hope this helps.

Load 'em up n choot 'em!

I haven't noticed an accuracy difference, but I really haven't paid much attention to it.
They usually iron themselves out in a few firings.

Piling on - same same. Worst case, an extra step of diligence would be to check the weight and internal volume of a select set of both types to ensure you ACTUALLY have equivalent brass (which is largely the point of sorting by headstamp in the first place, right?).

I have some in 38 SPL brass with two cannalures that have been reloaded 40+ times and they are not a problem. I doubt yours will be a problem either.

 

[sequins]

Yeah I also don't notice any difference. I sort my revolver brass by headstamp since it's so easy to do though, so if it does make a difference hopefully it's consistent!

In 45 Colt you should be doing a roll crimp into the bullets crimp groove so I don't see why it would matter in the case.
