Thanks guys I wanted to make sure before ordering the pre-fit barrel. I am wanting to do a 22BR for groundhogs using the new Hornady 53 grain V-Max. I asked Pac-Nor to email me a copy of their reamer print and Penny sent me five different prints. I think I found the best reamer for my build that will work with Lapua brass and have minimal lead to work with bullets in the 50 to 60 grain range. The reamer has a .248 neck for minimal neck clean up and a short neck chamber which should not be problem with the shorter bullets I plan to use. I have a email in to Pac-Nors tech line to confirm my reamer choice and to confirm they do the large shank barrels.
