Hi Shane, if you're going in for Lee reloading gear go for the breech lock challenger kit as you get 13 (I think) shell case holders and the lever prime system which in my opinion is superior to the one that comes with the anniversary kit, if you go down to the bottom of this page and go back 5 pages, scroll down, 'til you come to PKL's thread "Taking the leap, question around reloading, bullets and powder", go to reply #7, this goes into a bit more detail, hope this helps ...callie
