If the shock waves shoot good for you I would use them.I have taken several deer with the sst and shock wave from 48 to 234 yds in 45 caliber and 50 caliber,all complete pass throughs.
Just saw in the new T/C catalog that they have a bonded shock wave this year.These may be the way to go too.
Never did get the powerbelts to shoot in an encore ,but they did well in a knight 45 caliber (225 grHP) took one at 155 yds with it and complete pass through.
The 250 gr barnes works great,but shot a big 8 pointer using the 195 gr barnes,@70 yds,no blood or hair,found the deer about 4 days later.Nice 8 pointer with 17 in spread.Won't use those again.
