Safe to fire a shell thats been over crimped?
Was trying to get the die adjusted where I wanted and ended up putting an extremely hard crimp on a .45LC. The edge is flattened into the canelure. Will this cause excessive pressure or will the brass expand the same as the others?
BTW, I have started seating in one operation. Then I remove the seater plug and crimp separately. It still tends to shave off a tiny ring of copper? Is this likely due to slight variances in length? The COL is about. 003 to. 005 longer than theyre supposed to be but that doesnt really affect anything.

Fire as normal, your brass life may be reduced but no danger in shooting a heavy crimp. Be careful the brass does not blow off and lodge in the forcing cone or chamber but you will see that on the brass when you extract them.
UNLESS
You are shooting full power OMG loads on the edge of sanity, then all bets are off, YMMV.0 -
Your overcrimped round will not blow up your gun.

That is a bad sign.
What type bullet are you using, plated?
You must flare the case mouth enough to start the bullet without scraping metal off its sides. All the Internet Experts tell you to flare the bare minimum so your brass will last longer. Well and good, but if you deform the bullet and hurt accuracy, brass life is a secondary matter.
It will help to deburr the case mouth, too. Don't put on a heavy bevel that would weaken the crimp, but definitely break the sharp edges, especially inside but also out.0 -

So you think i need to flare the cases deeper?0 -
If the case is"shaving a ring of copper" during bullet seating, yes, you need a little more flare. If cases are varied in length, you need to flare the shortest enough even if the longer ones get a little too much. Since most plated bullets don't have a crimp groove, I assume you're using regular jacketed. If some of your cases are much longer than the one you use to adjust your crimp die, you'll get some over crimps. The only resolution for this is to trim all cases to same length. 0 -
Is what you're getting a tiny ring of brass from the case, or copper from the actual bullet jacket? I've had the tiny brass rings on occasion, but I've never had a copper one. When I don't bell the cases enough I get crumpled cases instead of shaved copper..[:(] 0 -

If you REALLY over crimp the round...it will be difficult to put in the cylinder. 0 -

My guess is you are already to deep.0 -

There have been a few times when I was adjusting the die for crimp after seating the bullet to OAL...that I forgot to back way off on the seating "plug"...[:0]...crimps and OAL can get VERY ugly when you do this[;)]0
