There is a NBRSA tournament coming up near me and I would like to compete, but since I've never competed before, I'm not sure if this is one I want to start with. Could someone please tell me what VFS & HTR stand for? I'm pretty sure the second one is Hunter Class, but reading the rules, I can't seem to find VFS and the type of gun I could shoot. I have a Remington 700 XCR Tactical Long Range in .223 that I like to shoot off of a bipod and rear bag. I do have a front bag to shoot from if required. A little info please.
