so a .502/3/4 might make them to tight to get down, but totally just guessing...
It just occurred to me that the Maxis will be sized .508-.510 on the top band. I don't know if the sabots would reach that far but probably wouldn't. The lower bands are probably around .503 so without resizing, it may not work well at all. But BS, BJH, or NE conicals sized to .500 just might work.
