I thought the bullet diameter on the TC XTP Mag Express sabots was .452. They come with the black sabots. I thought I had to buy the same color sabots. Am I wrong? I want to buy some of the HH24 for my XTP'S because they load really tight in my Knight and I just bought an Omega tonight and have heard the XTP's are tight in them also. $169.00 at Walmart. I couldn't resist!! I don't want to order the wrong sabots!
