I am only guessing... but from what Triple & says I would bet you have a bullet supplied with a MMP HPH-12 sabot. MMP now makes two varieties that are thinner - the HPH-24 (50/45) and the newer and thinner 3 petal EZ (50/45) sabot. The thinner 3 petal is not listed yet on the MMP site but by calling them you can get them. Might get a package of each and see what you gun prefers. I do not find where you list the type of you are using - but in the ML market that does make a difference because of the different sizes of bores between manufacturers. T7 also suggested Harvester and they also make two of the thinner sabots a standard black and a "crush rib" that allows easier loading.
