This cut shell thing ain't for 22 shot shells, nor for reloaded shot shells, though one could probably do it with reloaded shot shells if the crimp were made real strong, somhow.
I've found that many of the current brands, probably import, don't send the slug out properly and especially if the load is a magnum, as the long charge of shot seems to be unstable in flight, whereas standard field loads and espeically the light dove and quail loads tend to shoot most accurately at longer ranges. The nose heavy with long light tail seems to stabilize best.
The only way to know is to try whatever ammo you are carrying, and if it works fine, if not you'll know before peppering an amimal and not killing it.
By the way, game laws in Michigan back from 72 when we left and earlier, listed cut shells as a big game load, legal to carry only in big game season. -- In other words, one might cut them johnny on the spot. for immediate use, and beat the no carry rules, but have to do some intense explaining on how he punched a 12 guage hole in a critter with a shot shell!
Someone asked for autopsy reports. That would be real nice. I've shot only a lion close up enough to have the shot act as a cut shell would. The whole wad stayed inside the lions neck, and the lion stayed EXACTLY where it was when the shot hit! I expect a hit in the ribcage would show a well dispersed batch of pellets, but never asked of the people I know who killed deer with them. All have reported kills as quick as lightening, but nothing else. Good enough for me.
