Come on man!!
How much spread do you think you're going to get at house distances?
Assuming that's S&B 00buck 2 3/4 inch, which is what it looks like, I get about an inch every three yards out of my cylinder bore 18 inch 870 Police Magnum with that exact load, which is just fine by me.IIRC the old rule of thumb was 1 inch of spread per yard of range. This of course varies with ammo and choke.
I go through about two cases a year in non-panic times.
