22 smooth twist barrel

[RBAZ]

Have a crown in 22, does anyone know which weight pellet the smooth twist x barrel was designed around?

I don't have this gun but I would assume the 15.something and the 18.1 grain JSB would be lights out.

Pretty positive it was designed around the 18.1gn JSB.

It stacks 18.1’s at 35 yards, have not tried the 15’s yet.
