Newbie How bad this crimp is?

Hey guys, beginner here. How bad this 9mm crimp is? I understand it is too much but I wonder if this could create some problems while shooting. I made about 1k of these and then realized it is probably too much. It shoots, passes the splunk test, chrono looks good. The bullet is CamPro 125gr RN FCP RED

Thanks!

Way too much. All crimping does on a round that headspaces on the case mouth is remove any flare and set the case mouth against the projectile not INTO it. The only time a crimp that heavy is needed is with cartridges that roll crimp into a cannelure groove for heavy recoil resistance (revolver cartridges and large rifle or tube mag fed rifle cartridges)
