Cayugad,
I called Hornady the other day and the gentleman on the phone told me that they manufactured the Shockwave bullet for T/C but didn't provide the sabot, just the bullet. So T/C puts their own sabot on the Shockwave/SST bullet which must make for the slightly looser fit in the bore. I have read posts where many others like yourself say that the Shockwave loads a little easier than the SST's. I just ordered a 30 pack of the Shockwaves in 250 gr. from Cabelas. Can't wait to try them out to see if they are shooters in my gun as most everybody else seems to have had good accuracy and performance on game with them. Good luck w/ the new Knight rifle also!
