The Patternmaster Anaconda ‘SSS’ Sporting Clay is a 12 gauge tube for Benelli Crio and Beretta Optima Plus shotguns, machined from 17-4 stainless steel in a silver finish. Its patented Coil Zone “Gas over Constriction” design stabilizes the wad for even, consistent patterns, throwing a Light Modified pattern effective out to about 40 yards — a versatile choice for sporting clays. The tube extends roughly three-quarters of an inch past the muzzle and is diamond knurled for quick hand changes between stations. Not for use with slug ammunition; loads at 1550 fps and under pattern best.
