Plan on using mine for deer and pigs. Already took one pig with it. But, I had my .40 SWarrel and ammo in it when I began the stalk. 100 yards into the stalk, I remembered I had the conversion barrel and ammo in the gun. Too late to turn around, I completed the stalk and took the boat at 15 yards with the .40 S&W ammo. It worked.
Next time, I'll have the right barrel and ammo in the gun.
