I was reading the deer firearm regulations today, not sure why, but I thought I had better check it out since it was news to me we could use .30 cal bottle neck cartridges in pistols. Anyway, I have a NEF Huntsman .50 cal I am planning on using during muzzle loader season. I also have changed the breech plug to one that uses the .25 ACP case with a small rifle primer. Now I read this, bold and underline are my additions:
"Muzzleloaders: a single or double barreled muzzleloading firearm of at
least .45 caliber shooting a single projectile through a barrel of at least
sixteen inches in length; must be percussion cap (a shotgun primer is a
legal percussion cap), wheellock, matchlock or flint type ignitions only,
except the Connecticut Valley Arms (CVA) electronic ignition shall be
legal to use and only use black powder or a “black powder substitute”
such as Pyrodex. Modern smokeless powders (nitrocellulose-based) are
an approved blackpowder substitute only in muzzleloading firearms that
are specifically designed for their use."
Since the breech plug uses small rifle primers would it still be legal to use? I know the principle is the same, but sometimes the wording can mean things that were never the original intent.
I do notice that the way it is worded, you could use a .45 cal muzzle loader and shoot a .357 sabot. It just says "muzzleloading firearm of at least .45 caliber" which shots a single projectile. It doesn't say what the projectile size has to be.
