    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?

    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.

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

    Hope this helps.

    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.

    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.
