im basicly a shotgunner and iv got this drilling.. i pattern, do pennetration tests, figure velocity/pellet size difference, figure average shooting distance and on and on and its imprtant with all the different kinds of shot game sizes,etc available.. mostly if you follow factory recomondations for loaded shells youll be ok.but im reloading for this one. . i tend to cary this over to rifles, and lloyd your right, its a single pill, put it in the basket and the deer is dead.. if i dont have enough power for shoulder shot ill have to go for the lungs.. so a hard cast bullet may be my best luck for an all round deer bullet with this 200 grain 1300-1400 feet per second slug.. its strange it has a slow twist rate, 1-24.. it tumbled when i dug some bullets out of the dirt.. this could work to my advantage and could work as a disadvantage as to where i hit it.. there i go over analizeing things again :oops: ... thanks dave..
