I think someone had the pistol minimum and the rifle minimum mixed up. I believe that .243 is the minimum for pistols. I know that .357 is the minimum for rifles.
"Rifles with cartridges that fire a bullet of
.357-inch diameter or larger; have a minimum
case length of 1.16 inches; and have
a maximum case length of 1.625 inches are
legal to use only during the deer firearm season.
Some cartridges legal for deer hunting
include the .357 Magnum, .38-.40 Winchester,
.41 Magnum, .41 Special, .44 Magnum,
.44 Special, .44-.40 Winchester, .45
Colt, .454 Casull, .458 SOCOM,
.475 Linebaugh, .480 Ruger, .50
Action Express, and .500 S&W."
And if anyone has more info on that shortened .45-70, I'd love to hear some specs.
