I went out and ordered a 375 Ruger in a Savage 110 Brush Hunter. I got a box of Hornady 270 gr ammo when I picked it up. I haven't shot it yet. It seems nice. Has an adjustable stock and a 3 shot magazine. Has the accutrigger too. Has rather tall iron sights. I picked up a scope mount and rings. It's threaded for a muzzle brake but I don't know what thread it is. Looks to be 9/16 or 5/8 . Does anyone know what thread this is?
