My omega is probably as bad as any. Mine refuses to allow a second shot with anything I have tried up until I found Black Mag'3 powder. It is expensive and difficult to find by the Omega loves it. I have loaded and shot four in a row without a swab. I can sometimes get American Pioneer to allow second and third shots but it is not a clean as BM3. I just got some Goex Pinnacle to try but the temperature is too hot to shoot yet so have not tried it. The Omega isa long barrel and Black Mag'3 works best in a long barrel. It lights off a little slower than powders like Tripple Seven but with the long barrel it actually gave me higher velocity that equal volume of T7 ffg.
