I use the sst (shockwaves) in all my muzzleloaders.They work great on deer and shoot very accurately.This is a pic of a 6-shot group I shot last year @100 yds using 195 barnes200 SW and SST and even a 250 gr SW.Shot with my 50 cal encore. Shot a 1/2 in group @200 yds last week in my savage and 250 gr SWaves.
