I'm working on putting together a lighter weight hunting/ field course match rifle. I'm going to be running an 18-20 in carbon fiber barrel with a suppressor. I just can't figure out what would be the best action to use. I've look at the defiance xm actions which I like down side to them is that i have to have the stock custom inletted for the action. I'm also looking at the nucleus and the standard tenacity or possibly a bighorn origin. My last choice is a 700 with some action work done to it so it will feed correctly. Would like some feedback on what other people are running.
