Buel
I've just shot the CVA Optima! What a dream shooter! Absolutly no blow-back at the breech plug! You can load the 209 primer by hand and remove it just as easy. Used 2x50grain Pyro pellets(some crud ring formation after 5 shots) and some 100grains loose American Pioneer Powder, pushing 245hp/pb's. Great accuracy!
If I had to do it over, I'd buy the Optima or Optima Pro--way better than the Kodiak or Firebolt/MagHunter!
You may want to change powders again to FFFg APP

Way less swabing, non-corrosive and no crud ring, and had same POI at 50-70 yards
