Should have got the regular Harvester EZ-Load sabots for that bullet. I use them often with the 45cal version of the XPB in a tight bore. They still load pretty easy. Lands in that rifle are exactly .500. 50x44 sabots compress a tiny bit more so they feel even easier to load. Most of the people i know use the Harvester smooth sabots instead of crushribs in the CVAs with great success.
