I use the TC Cheap Shots (240grain hollow points - all lead bullets) with the Mag Express sabots, I use to use 240grain Hornady XTP bullets with the same sabots, but found the Cheap Shots just as good as the XTP's on deer. And they're a lot less expensive.
FWIW, they both have the same POI with two 50grain T7 pellets, so no re-sighting needed with either bullet.
I don't think there are many people that use a round ball out of the Huntsman or Sidekicks.
