Our shells are safe to shoot in Vintage Guns. Even with Damascus and Twist Steel barrels!
Of course after a reputable SxS gunsmith has given the OK.
(With the exception of the Pigeon loads, A-5, Heavy Hunting)
RST manufactures both 2" and 2 1/2" shotgun shells, as well as 2 3/4" shotgun shells that offer the widest range of loadings for classic and older guns for shooters seeking low pressure and high performance with reduced recoil.
