I just got my first 22 HP today. The bore is in exc shape. I did a chamber cast along with an inch of the throat. My groove diameter looks like .228+. I formed some 30-30 brass down and the final pass into the RCBS full size die left the shoulder about .003-.004 too long and the lever is just short of closing. So I will either grind about .020 off the top of the shell holder or the bottom of the die so I can set the shoulder back a little more.

I do have some new Norma brass so I am going to load and shoot those hopefully tomorrow. I will use the Buffalo Arms .228 60 grain bullets.
