I was recently at a buddy's house and was checking out a rifle he has. He doesn't know much about it and I was wondering if anyone here could help me out. It's a bolt action rifle in 250-3000 AKA 250 Savage and the barrel reads "Johnson" on it. I did a few searches online without any help. His uncle used it for Antelope out west a couple times. Does anyone else have any knowledge of a "Johnson" gun? Thanks in advance for any help.
