Don't forget to try the Shockey Gold. Its a bit more compressed and more consistant than orig. poineer. Pellets are more consistantly sized and a bit smaller in size so they now just drop down the barrel. I sell pyrodex,T7,American Pioneer, and Shockey Gold,all are available to me and I choose Shockey Gold. Have found the accuracy acceptable out to 200 yards with the right bullets(TCA SHOCKWAVES-EZ GLIDE)
I currently have 5 .45 cal shooter guns(Knight Disc, T.C. Enchore, T.C. Omega and 2 CVA OPTIMAS)all sighted in with above combination of powder and bullet. They are all also topped with Nikon Omega 3-9x40 BDC (bullet drop compensator) scopes with Dura sight Quick release rings.
These guns are shot 100's of times for two years at shoots for my customer base and the Shockey Gold has yet to fail me.
Just a sales mans opinon though.
