For the house gun.....The first round in my M1Super 90 slug gun is a 3 dram 1 1/8 ounce of 8s...all the rest are 2 3/4 inch Rem #4 buck. The first one??? If they can't see ya they can't hurt ya. Cold thought, I know. Even a hit anywhere on the body inside the house is going to be VERY painful. The following 8 #4 buck if needed will probably be fatal. One story.... BTW. I have shot an awful lot of slugs and deer. Foster slugs work ok out of some guns clear to a hundred yards. Sabot slugs in a scope sighted IC/Skeet smooth bore are good for 150 yds if you get 'em sighted right. Rifled bore w/sabots finding the right one for your gun/bbl; are seriously good up to 200 yds. It does take serious testing to find the right combo. Slugs are clearly the wrong ammo for a house gun
