Yeah, I had a 20" Green Mountain that was under 7.5 but it was fluted so it wasn't legal. Too bad, because it was a nice barrel. I swapped it out for a 16" Elysium bull barrel from J&G Sales and came out money ahead after I sold the 20". I'm very happy with the new barrel, but it's really overkill for this match. From prone I can easily hold the 10 ring at 50 yards even with my cheap Walmart Savage MkII.
Hopefully the weather will cooperate. We're supposed to get some rain this weekend, so make sure you bring a shooting mat, tarp, etc so you don't have to lay in mud. I probably will not shoot in this first match just to make sure everything works smoothly, but I will also have a couple extra rifles if anyone wants to give it a try. Just bring your own ammo.
