Ok so I have a rifle I bought off a friend, believe it's a 111 in .300 wm. It is top bolt release, detachable staggered feed mag, and doesn't have the accuracy trigger. I recently shot my friends GAP rifle and even Helen keller could shoot sub moa at a thousand yards with this thing but he also spent ALOT on it. So I have a new criterion heavy barrel for my savage and would like to put it in a new stock or chasis. If I went with something like the choate tactical stock would I need new bottom metal for it to work? What are my options? If I spent more money for like a mcmillian a4 would I need bottom metal for that, since they say you must send in the dbm for fit. Or is a chasis system easier way to go
