Hello all, new to forum. I have rifle given to me in 303 british that the barrel is shot out. Please help identify what i have, as I would like to rebarrel in either 308 or 30-06 if possible, as that is what i'm allready shooting. I also don't know if bolt will work as 303 has bottom rim on cartridge and 308 and 30-06 do not. The rifle has a timney trigger and the stock is nice so I think this might be worth doing? Please give thoughts and suggestions. Thank you.
