Son's cva wolf will shoot 250 grain Barnes over 90 grains of powder with very good accuracy. We use cast 45 caliber 250 grain bullets unlubed in the sabots for practice and sighting in....cuz the Barnes are just too expensive. I agree with the 90-100 grains powder being all you need. My guess is that 240 and 250 grain will shoot well in yours. Your gun has a 1 in 28" twist so you could even stabilize heavier bullets. Have used triple 7 loose, Goex fffg and regular pyrodex. He used 209a fed primers but you may want a milder primer for best accuracy.....just what we had. They don't seem too picky and breakdown for cleaning is easy.
