The Shockwaves are definatly easier to load in the MagBolt I have. The MagBolt and hunterbolt are basicly the same gun. If you have any full caliber conicals you could swedge one end of it out a little larger and then push it through your bore to get an accurate measurement of the bore and groove dimentions, that will help in deciding what sabots to buy if you need to get something else. It also helps to know this info when talking to Harvester, or who ever, aboutsabots for you gun.

Good luck and keep us posted.
