@ruggyh,

Good info as always.

I believe I am following common sense approaches to reloading. My first 5 loads were minimum recommended charge for Alliant 2400 at 31 grains for the Raniers.
I'm not increasing the charge until I get control of the bullet creep. And by control, I mean I know precisely what neck crimp works best and I've fired quite a few rounds with consistent results.
BTW, Ranier also said to buy a Lee Factory Crimp die. Unfortunately, they do not make a die for the 500. The best they have is you can send them seated bullet and they will custom build one. That's crazy being that there's numerous projectiles that would be seated differently for each one. Heck of a deal for them as they will charge $30 for each one. Not very cost effective.

Thanks!
