Many of the brands you named comes with a thick sabot. Get some of the MMP HP-24 or Harvester Crushed Rib. There are also some new two or three petal sabots out that are said to be thinner but I never tried them. Unless that's what was on the Super Glide Sockwaves I purchased.

The first time I shot my CVA Staghorn, I ran into the same thing you're describing and actually broke my wooden ball short starter. A thinner sabot is your solution and should have you shooting 10X in no time.
