"Why Crimp?"

Through out my Reloading I've found that a Crimp reduced the
size of my groups on target.

I first noticed it with my AR15 5.56/.223. I had read about Crimping,
and gave it a try. I got better groups on target. I also got
away from using Military Brass (I believe it was not sealing in
the chamber correctly), my groups got smaller.

I truely believe with a light or medium Crimp, it holds any Bullet
in place a little longer, and allows the Powder to burn correctly.
I've noticed cleaner Cartridges also, especially when using
Alliant Unique in Handguns.

I really like to use the Lee Percsion Factory Crimp Dies, whether
its for Rolled Crimps on Handgun Cartridges or the squeezed
Collet Crimps on Rifle.
