Another glance shows several other states where .223 would not meet the minimum caliber or other restrictions.
Alberta- .23 and up centerfire
Connecticut- .243 and up if legal in your area
Delaware- shotgun/muzzle loader
Illinois- Shotgun/ML/Pistol only
Iowa- .24 or larger centerfire only for antlerless season in part of the state.
Kansas- .23 or larger centerfire (actually says larger than .23 so maybe .24 is the mininum)
Mass- Shotgun/ML
Minnesota- .24 and up centerfire
New Jersey- shotgun only
Nova Scotia- .23 and up
Ohio- Shotgun/ML
Quebec- 6mm/.243 and up
Rhode Island- shotgun/ML
Saskatchewan- .24 and up
Virginia- .23 centerfire and up
Washington- .24 centerfire and up
Wyoming- .23 centerfire and up
It’s not legal here in Indiana either. We just opened up the door to the various .30cal/7.62 flavors for deer. Previously you had to use shotgun, .357 mag, or .44 mag.
