Definitely worth a look - Winchester Defender Shotshell 12 Gauge 1 oz 2.75" Shotgun Buckshot Ammunition

I ordered a variety of 12 gauge self defense loads from Optics Planet for my Shockwave. The lower recoil loads like these Winchester Defender shells are definitely preferable in the Shockwave. The plated pellets are a must to avoid deformation when packed behind the slug. Whether the combination of slug and pellets is better than a standard slug or buck load is debatable. At close range the pellets don’t deviate much from the slug thanks to the buffering but after impact there’s no telling how they’ll behave. Damage for sure. If you can get these try them and decide for yourself. I was glad to find them on OP.
