I also live in billings, tell us about what your shooting?
My latest and greatest is an AR-15 in .204 ruger. I have Z-15 frames from Defiance Machine out of Columbia Falls, MT. A 26" barrel from White Oak Armament with a bolt to match. JP lo-mas bolt carrier and adjustable gas block (hoping to turn it WAY down). I got a smoking deal on a rock river 2 stage trigger so I'm gonna run it and compare it to the Geissele I have on my .223 yote gun. I havent stepped into reloading yet although that is where everything is leading. I also have a rem 700 in .270 a tikka in 22-250. I LOVE the feel of the tikka but havent got to shoot it much. None are long range hunters, the .204 should be (hopefully) my first step to precision PD hunting. A few more days and that WOA barrel will be here, I cant wait!
