It’s an old Ruger m77 so pretty short mag box, I didn’t realize how long those 213’s were til you said that. The 225 sledge hammers look like 600 would be pushing it for energy but I hear they’re a great bullet so I may just limit my max distance to 5ish if I go that route. It’s a hand me down rifle from grandpa, really want to kill a bull with it while he’s still around but after that it probably won’t see much action unless I really get it shooting well.
