I have the carbon barrel bxr....and I love it..I also have a 230 yard range in my back yard that I can ding 6 inch swingers with it..any ammoJust bought a Bergara BMR .22 Bolt Gun and I am pretty happy so far. Only shot at 50 yds and had @3/8" 5-shot group with 45-year old Winchester Wildcat ammo. Hope to better that with good ammo and see what it will do out to 200 yds.
