If one were to buy a shot out Remington 700 varmint and had the barrel rebored to .45 or .50 and had a arrowhead sporting goods primer conversion done would it not make a really decent muzzleloader?

Illinois
Muzzleloader Regulations
Legal Description:
“Single or double-barreled muzzleloading rifles of at least .45 caliber shooting a single projectile through a barrel of at least sixteen inches in length. A muzzleloading firearm is defined as a firearm that is incapable of being loaded from the breech end. Only black powder or a “black powder substitute” such as Pyrodex may be used. Modern smokeless powders are an approved black powder substitute only in muzzleloading firearms that are specifically designed for their use. Percussion caps (shotgun primers are legal), wheel-lock, matchlock or flint type ignition only may be used, except the Connecticut Valley Arms electronic ignition shall be legal to use.”

Very interesting
