I am shooting a Browning A Bolt in .300 WSM. It has been great for hunting I typically shoot deer out to 420 yards and elk out to 650. I started shooting paper and a gong out to 800 this summer and getting 1 to 1.5 MOA groups. The question I would like to get some thoughts on is on a budget would I be better off to buy a new match grade shilen barrel and a McMillan stock to get more accuracy from 300 to 1000 yards or should I just enjoy what I have and save for a "real" long range build? Basically is it worth putting 1k$ into a Browning A Bolt?
