In response to K Bacon, my new Omega seems to like just about everything my Black Diamonds like - I guess they have the same barrel. Try a 250 grain T/C Shockwave ahead of 130 grains of Pyrodex pellets (two fifties and a thirty). This load shoots as good as most centerfire rifles in my Omega and offers 200 yard performance, if you need it. Good luck. Roskoe
