I use the regular Harvester sabots with these bullets and they work great - same as the Shockwave. And they are actually legal in Colorado - just not during the designated muzzleloader season. I have used them a number of times during some of the late and dispersal rifle seasons.

Also, I have heard that Thompson Center will test one of their guns, sent back with suspected of accuracy problems, with a 250 Shockwave ahead of two 50 grain Pyrodex pellets. It is their "go to" accuracy load.
