Gentleman, I got my .338 up and running now I am trying to find a place to shoot. Talked to Red Castle but the outdoor slots are closed. I can go out for their month 600yard shoot but the class they want me in is "F" so I cant use a brake and I'm not going to shoot this thing without a brake.. Where can I shoot more than 300 yards? Going to USSA this weekend just to get some trigger time but can only go 300. Any help please..
