Currently it's dialed in perfectly at 100 yards since that's all I normally have around here to shoot. I'll have to double check, but I believe it's around 11.5 minutes I need to dial in shooting 175gr gold medal match out of a 20" barrel.
The guy that I am going with has a 308 with the same barrel length, so I'll dial in whatever he uses to start with. But the two vertical targets is a good idea to start with. They have a 6" and a 12" gong out there too. Should be a fun day. Might even try it with my Wilson Combat Urban Sniper too.
