I went with a 50 yard zero using slugs, which felt like a good “general purpose” zero for my Aimpoint T2. A couple of inches high at 25, a couple of inches low at 100 (translation: “minute of man”). This is for my home defense load, which consists of Federal Flite Control 00 Buckshot with some PDX1 segmented slugs on the side saddle. Given how tight the Flite Control stuff patterns, the slug zero works for me. YMMV depending on your preferred ammo.
