depends on the bore diameter or your gun. some guns are tighter than others. My wife picked me up a pack one day thinking they were all the same.

I went to use them in my guns to not waste or piss her off thinking she got the wrong sabots..

my older elkhorn gun they fit just fine, in my hawkens however they slide down the barrel faster than a kid on a slip and slide lubed down with astro glide.

I was almost afraid of using it that morning for aiming down from my tree stand I would see the little booger fall out the end of my barrel.

The plastic jacket is just thinner on the super glides.. the bullet/sabots are the same as regular shockwaves though.
