FX Bobcat 25 cal

I've had the same questions as you with my Royale 500(.25 cal). It's the exact same platform as the Bobcat. The Original Smooth Twist barrels WILL NOT shoot slugs with any kind of acceptable accuracy but they ARE, arguably, the best PELLET barrels ever made. You might want to PM Glem.Challey (sp?) with your query. BTW, I've tried hybrids, Varmint Knockers, NSA, etc. The OST barrels just don't like them.
