NO!!!!

A Lee crimp die will NOT "crush" ANY heavy jacket OR monolithic .458" bullet designed for heavy or dangerous game!

A little bit of "poetic licence" here by me with the "crush".

I have 8x68 factory ammo with a Lee style crimp and they do "crush" the projectile because when they were pulled I couldn't reuse them as they would "fall" into a sized case.

They were H-Mantels,Cone Points and 196 grain solids.

Agree they won't crush a monolithic bullet.
