I was given a 770 in 7RM. I have a great 7RM already, are these action worth anything to build on? Gun has less than 50 shots thru it. Was thinking maybe turning it into .264 WM or what other options? Would the bolt work on a 300wsm? Reviews don't sound to good on them. Trigger is not bad 3.5 just a touch of creep, stock is junk for sure.
