I hear you. My last attempts were with 100 gr of Triple 7 and I tried both the Powerbelt 245 & 285s. All over the place. It is a pain to clean and even more of a pain to to remove the breech as you said. I'm gonna give it one more try and try Cayugad's recommendations and go from there ..... after the season. I borrowed a buddies Omega for opening day here in VA and have sat in the woods with my bow ever since.
