I started with a Lee press and Hornady dies....

Quote:
Does the die seat and crimp at the same time? Or do you seat then adjust the die and crimp.
Either way.....

I have had best resuslts when I seat and crimp in a spearate operations, and now I use a Lee Factory Crimp die to do most all my crimping now.....

With 30/30 cases, in particular, I had more than a few buckled shoulders when I tried to seat and crimp in a single operation. YMMV.

There is some debate about whether or not to crimp at all or not..... I always do, as most of my rounds are hunting ammo, or practice for hunting ammo .....

-It has been my experience that I get smaller SD (and group size) when I aply a good crimp. Consistancy is important.

- Hunting ammo may get chambered from the magazine several times- I want that bullet right where it was when I seated it. I crimp. Others say this is a waste and neck tesion will keep that bullet there ..... fine. I'll crimp mine because it works for me.
