    I picked up a box of 20 of these boogers and I see the brass has what appears to be some cannelure-lookin' rim about halfway up the brass. What is this? Why is it there? Will these be reloadable? If so, what can I expect them to look like post-resizing during reloading.

    Thanks, as always.

    I have seen the same thing on Magtech brass in 45 ACP. I reloaded them without any problems. Only reason i can think of them to be there is some sort of crimp they apply to the case.

    It maybe purely cosmetic to justify the price.

    Back in the day, cases were filled with black powder, and the bullet sat on top of the case-full. It could not go deeper into the case.

    Nowadays, with smokeless powder, you don't use a full case. It is possible for the bullet to be pushed deeper into the case. I have a small collection of factory and reloaded ammo (mostly 9mm and380) that the bullet nose would get caught on the loading ramp, and the slide shoving it forward made it quite a bit shorter than the others.

    Some ammo companies put a cannelure in their case, to make a ledge for the bullet base to sit on. This helps to prevent bullet set-back. Generally it is done with the older rounds - stuff that was originally loaded with black. MagTech's 45 Colt rounds are a great example. You've got, probably 3/8 of an inch of airspace between the powder and the bullet base. So the bullet sits on that little lip.
