■ Only conical bullets made of lead, lead alloy, or federally-approved nontoxic shot material, with a length that does not exceed twice
the diameter, and round balls made of lead, lead alloy, or federally-approved nontoxic material, used with cloth, paper or felt patches are allowed during muzzleloader-only seasons and 600 series hunts where there is a weapon restriction of shotgun/muzzleloader only or archery/muzzleloader only. It is illegal to hunt with non-lead bullets except for those made of federally-approved nontoxic shot
material, jacketed bullets, sabots, and bullets with plastic or synthetic tips or bases during muzzleloader only seasons and 600 series
hunts where there is a weapon restriction of shotgun/muzzleloader only.
Lead conicals are really the only option. Cabelas online has the Hornady great plains, Thompson center maxi hunter and maxi ball. I shoot the White bullet but they quit making them. Make sure you have no fiber optics on your sights.
