The bottom 3 groups are all inside an inch at 100 yards with the scope set at 4X. Factory ammo. That's not my idea of a scattergun. Everything is tight with loc-tite and scope eye relief is right for me. Nothing is in the way of ejection.
Right now, it has the M885 in it (not 855, my mistake) because POA = POI. M885 is the green tip 62 grain fmj. If I decide on another load, scope adjustments will take care of that. I'm still trying different loads. It's fun.
