Federal Premium Power Shok 20 Gauge 7/8 oz Power Shok Sabot Slug Centerfire Shotgun Ammo, Rifled Slug Shot, 5 Rounds, F203 SS2

I switched to these after using the Hornady SST sabot slugs. These are about half the price and work perfectly. At 110 yards, after I got it sighted in with a scope, I put the last 3 down range and got under a 4 inch group. I didn't use a rest or bi-pod so I think that's more than acceptable for a slug and would kill a deer with no issues at all. The gun I used was a Mossberg 500 20 gauge pump with a fully rifled slug barrel.
