I appreciate the slight flare in the 40 brass @R93, would a slight and i do mean slight crimp just take that slight lip off the case or is it so negligible??

I will re measure OAL and seat projectile out as far as i can in the mag AND maintain function

My seating die (Wilson iirc) allows you to adjust the crimp.
I just adjusted it until I got an flared empty case back to the resized diameter at the case mouth, and left it.

It has been setup for a while and I haven't had to adjust it.
You should be able to see all of the case mouth thickness around the projectile.
Mine all still have the serrated pattern from when orginally cut to length on them.
