Hi Brandon and welcome. No Sir, Buffalo Bore's website says this round is too long to properly cycle in a Henry. Cheers, stay safe and enjoy! Henry says: Our Big Boy's can handle all the +P pressure out there even Big Buffalo Bore ammunition as long as the rounds are not to big (over 270 gr.)

No, the site states using +P ammo/reloads will void the warranty.

Hi Brandon, no sir, according to Cimarron, "Shooting any ammo like +P or reloads will void the warranty on the gun. Cimarron Firearms does not have any plans to make any guns that shoot +P ammunition." Stay safe & have a great day!

sorry they are not recommended by Cimarron
