If ppl cant understand the connection of weight, pattern density, penetration, and number of hits in the vitals then they are clueless and will never understand unless you shot a pattern of each in front of them with sheet metal as the backer to let them visualize the pattern density and penetration that tss offers. A lot of ppl are too ignorant or simply won't take the time to put the thought process thru their head. Do you have to shoot tss, NO, is it far superior, YES.
