) It seems to me, depending on the bullet used when the case is cannelured, that you've ruined the case because first, if a shorter bullet is used next time the case is loaded, it's going to "telescope" into the case until it hits the existing cannelure, and second, if you use a longer bullet, it won't be able to be seated to proper depth. Third, if the cannelure were to "iron" itself out upon firing the case would be weakened at the point of the cannelure. This would be especially true with a cannelure as deep as the one pictured.Might not be a problem on a more shallow one.
I just checked some Winchester SilverTip hollowpoints (.45 ACP) sitting on the shelf and they were done in this fashion.
Much of the .45 ACP military brass (M1911) I have also has a cannelure rolled into the brass. I've never personally seen one rolled as heavily as that shown in the above photo.
I've not found it to be a problem. I've been using/reloading this brass since the mid-70s, using primarily 230 FMJ and 200 SWC cast, without the issues you mentioned above.
YMMV
