Jason, yes sir, according to Henry All of our Henry .45-70 rifles can handle any reputable brand of factory loaded rounds, with standard and +P loads, standard profile bullets (round-nose, flat-nose, and hollow-point), and which are SAAMI (up to 28,000 c.u.p.) pressure compliant. They can handle all commercial loads except for those marked "For Ruger No 1 Only.". So you're good to go. Hope this helps.

Hi Jason and welcome. The Henry Repeating Arms Brass lever action 45/70 rifle can handle the much higher pressures of the new, improved 45/70 ammo. Tim Sundles of Buffalo Bore Ammunition signed on board the HRAP from the very beginning days of the project and provided 45/70 ammo in various bullet weights and ballistic capabilities, to include some of his 45/70 Magnum ammunition. Buffalo Bore has also tested +P in the Henry Rifles : https://buffalobore.com/index.php?l=product_detail&p=151
