The Carlson's Choke Tubes 41015 Winchester CORE Win Choke 12 Gauge Mid-Range is a Core Series 12 GA shotgun choke tube designed to optimize performance for a variety of field and range situations. Carlsons distinctive design fits most Winchester, Browning Invector, Mossberg Model 500, and Savage shotguns, delivering reliable mid-range patterns when everything from BB to Hevi-Shot is in play. This Win choke tube is calibrated for mid-range performance, ideal for shots at 20-35 yards with lead, and 25-45 yards with steel, incorporating a #2 MR/MOD configuration to balance density and pellet concentration for reliable performance across common 12 gauge loads, including lead, steel, bismuth, TSS, and Hevi-Shot. By tailoring pellet distribution at those distances, shooters can achieve consistent patterns without sacrificing spread for close encounters or long-range opportunites. Designed to be compatible with a broad spectrum of popular shotgun platforms, the 41015 model provides a practical, versatile solution for upland, waterfowl, and sporting clays scenarios where dependable mid-range performance matters most. Carlsons Choke Tubes combine rugged construction with precise constriction to help you maximize pattern efficiency and field performance.
