Hope you are doing well. I just got back from the NRA Annual Meeting in Phoenix, AZ.
The rule is 76 mm of course, but be aware a number of stocks are wider than that, particularly if slick stock tape is put on them. 76 mm converts into 2.992117 in the program I used. The NRA rule book states “shall not exceed 76mm (approximately 3 inches).
I knew you were out there some where. Concerning Nationals:
I'm having a hard time finding a campground near Butner. Any ideas on who to contact? I emailed Jeff Royer and he sent me to Ira Jones. Ira said there is one six miles from the range but it's pretty shabby. Where does John Brewer park his Limo.
