[QUOTE="Pdvdh, post: 1205349, member: 4191"] I agree with this, in the pursuit of optimum consistency, shell to shell. With my .223 brass, I have ~3,500 cases and they're not all trimmed exactly to the same length. The Lee Factory Crimp Die is very forgiving if these case lengths vary by 0.010" or even 0.015". The goal with my AR15 is minute of gopher, and the LFCD provides great flexibility while crimping these casings. In my very first comparison test, the 280 yard group size of the crimped ammo shrank to about 55-60% the size of the uncrimped ammo. To set the record straight, I haven't experimented with crimping any shells other than my .223 ammo in my AR15 so far, and I've only tested that gun on two separate outings. But the local shooter I know has tested LFCD crimped ammo in several different calibers in a number of different rifles. And I trust his testing as much as I do my own. [/QUOTE]
