12 ga 2-3/4 dram 1-1/8 oz of 7.5 shot. I don't like the idea of too much penetration inside a home. The pattern in most room sized areas is ablout 6-9" That much shot would do the job, no matter what the size of the shot is.
Once i had a BG coming in my bedroom window (in Florida). The sound of the 870 12 ga being functioned was enough for him. He nearly killed himself leaving.SJ said:You hit the first BG with a load of 12 gauge 00 and all other perps with him is going to run. :NO:
