Thanks for all the advice fellas! I just called MMP and they recommended I try the HPH24. The lady I spoke with said that she wouldn't recommend the HPH12 or the regular black because they would be too tight. She said that T/C guns have tight bores and the HPH24 would be what I want. She did offer to sell me all the other sabots if I wanted but she was trying to save me some money.

Like I stated above, I've tried the Harvester Black Crush Rib and didn't care for the results. Do you guys think I would see any different results trying the regular black Harvester?
