I could not see the reason he would want to purchase two packs of bulk .452 diameter harvester black high pressure sabots and a box #100 count of .45 caliber 250 grain Hornady XTP's, and I have never been able to find the Hornady SST's in bulk prices.
Why go through all that to try them out?They are both the same, Hornady makes the shockwaves for TC.He could just purchase a package of 20 Hornady 250 SSTs they come with the sabots,for $7.17 at Midsouth shooters supplies.
