A friend gave me a can full of those REAL bullets and I shot some just out of curiosity as I get an invite to hunt Colorado once in a while.
They just don't shoot like sabots,no one hole groups, but with a felt wad well greased and a dry one under it they would shoot 2.5 inchs[100yd] out of my Omega,but the heavy load was only 90 gr and they shot the best group with 80 when I tried to load up they went wild and leaded the barrel.
I would say they were usable at short ranges say up to 100yd but with that light a load long range like 150 and over would be kinda chancy. Lee
