Personal defense rounds - Winchester Defender Shotshell 12 Gauge 1 oz 2.75" Shotgun Buckshot Ammunition

Have been running these rounds in my house defense Remington 870 for years. Pattern is perfect at 10-20 yards. Will inflict catastrophic damage if used. Slug followed by 3 - 00 buck shot? I mean c'mon, its a no brainer what it'll do. Recoil is very manageable.
