Overview

Built for rifled .410 bore barrels, this load is designed to deliver a three-projectile column that places all projectiles on a man-sized target at 7 yards. It combines two .35 caliber round balls with a non-jacketed FTX slug, giving the round a purpose-driven layout for close-range defensive use. The slug is intended to engage rifling and strike nose-on, while the round balls are made from high-antimony cold-swaged lead to help resist deformation and support penetration. Because it is meant for rifled barrels, performance may be affected in barrels without rifling.
