I'm can say with ease I've done only a small amount of research on the shotgun slug for hunting. I know the foster kills due to soft construction compared to the sabot's speed. I know from recent experience that my 870 with it's 3" screw-in choke sends 1 ounces of soft lead to the target, accurately out 100 yrds. The wad was left as my trophy on the chest of the 200lb. PA doe it found last year! Yeah.. big hunks of lead! I need everyones advise on using the same 870 SP for Baar. Should the slug be of heavier construction or should the same Rem, 1-ounce Slugger be imployed. My buddy says.."it must be harder to pass thru" but I kinda fiqure the same load that busted deer will work.
