I also have an inline made by CVA - it's their Buckhorn Magnum distributed by BPI. The factory recommendation was to use Powerbelts. I was going to get some when I began reading some negative reports on their terminal performance. I bought bullets and sabots instead, but have had great difficulty in loading them.
Normally, Bore Butter or other lubricants are not recommended to use with saboted bullets - the plastic sabot is slippery enough to slide down the barrel after engaging the rifling. But I tried a little BB, just to see if it helped my situation - - it only helped slightly. I have tried two diffeent bullets and three different sabots - none of which load easily enough for a hunting situation. I purchased some lead conicals, and they load much easier. I'm probably going to get some Powerbelts, since I have heard that they usually load fairly easily.
Since you are new to ML, and if Powerbelts were recommended, I would get some of them first. After you are more familiar with the ML process, you might want to try something else. Just my opinion.
