Well... This rifle got moved to the back of the safe and forgot about through deer season and the holidays. I started messing with it again.
After some research I realized the rifle probably had a 11.5" twist. Verified that. Others had issues shooting 140s. So I picked up 120s.
Nice tight groups-as initially expected. Kinda bummed I'm limited to 120s- but it shoots them well and the deer won't care for them any.
Haven't decided if I'll keep it or not. Probably will hunt with it this fall though.
