Oh! You are right I forgot about that other caliber... I just don't deal with the 45's anyway the 45 caliber rifles...
RH1, just for curiosities sake, does the copper on those 40's roll over and into the nose of the hollow point a bit?
You know now you really have me thinking - In Idaho and I believe Washington, I don't think those 40's would be legal.
The rule in Idaho reads:
Muzzleloading Rifle or Musket
In any hunt, including general any-weapon seasons and short-range hunts, it is unlawful to pursue or kill big game animals:
With any muzzleloading rifle or musket that is less than .45 caliber for deer, antelope, or mountain lion; or that is less than .50 caliber for elk, moose, bighorn sheep, mountain goat, or black bear. Loaded with a projectile of at least .428 caliber.
The rule in Washington (State of)
(b) A muzzleloading firearm used for deer must fire a single, non-jacketed lead projectile of nominal 40 caliber or larger except that buckshot size #1 or larger, may be used in a smoothbore of 60 caliber or larger.
(c) A muzzleloading firearm used for all other big game must fire a single, non-jacketed lead projectile of nominal 50 caliber or larger, or fire a single, non-jacketed lead projectile of at least 170 grains.
I guess I never even thought of these rules until you mention the 40's other than in Idaho I knew the .428 limit was there. I wonder now about other states....
