Semisane I see the sabot you shoot is a H4540B I am guessing the H is for Harvester, 45 is the caliber of the rifle, 40 is for the projectile and B might mean Blue? I looked at my Harvester Crushed Rib sabots that are blue in color. The code I read is H14540BR So I am GUESSING these are the same sabots you shoot.

Mike.. the tan MMP sabots list on them not to be pushed with more then 80 grains of powder in the paper handout that comes with the sabots. So amazing velocities are listed with a mere 80 grains of powder, so you pushing 110 grains of Triple Seven must be pushing them in (guessing) the 2200-2300 velocity area.. does that sound right.

Sharpshooter.. you must be getting some over the top velocities with that kind of powder charge and them 185 grain Lehigh bullets. What sabots do you normally shoot?
