I have the Henry in 45 Long Colt. Magnificent!
Every box of ammunition produced in over 1/2 century by SAAMI and other responsible members worldwide has some form of the warning, "Use this ammunition only in firearms marked and chambered for this specific cartridge."
Don't be mislead about cartridge designations by ill-informed gun writers, layman gun nuts and irresponsible off-shore manufacturers.
To paraphrase James Carville, "Its the headstamp stupid!"
Read them. Good luck in finding ammunition headstamped with your mistaken identity.
Go for the 44 mag. Way better performance with little recoil, and sound blast is much lower than revolver
A Henry! Yes! I’d sleep with mine if my wife would let me.
