Hitting a thin skinned animal, like a bobcat, with a 150 gr .30 cal projectile results in a severely damaged pelt. It was an interesting concept.

Also when using a muzzle loader for deer it allows me to use a 200-240 gr .44-45 caliber bullet of better construction and profile than an all lead projectile for extended range over a 390-450 gr .50-54 caliber projectile.

I have hundreds of sabot rounds, plus the WDFW allows their use for hunting when using muzzle loaders.
