From Henry Repeating Arms:
Q. Can the Henry Big Boy withstand high pressure loads and should I have any concerns about the strength of the brass receiver?
A. The Henry Big Boy receiver is composed of a special material that is chill cast, heat treated and machined in such a way as to have the same tensile and yield strength as steel. There are no issues whatsoever as far as the durability and its ability to withstand high pressure rounds such as those made by CorBon and Buffalo. The rounds made by CorBon and Buffalo, or any other brand, must be made to what is called SAAMI (sammy) specifications in order to cycle properly. The SAAMI specifications relate to the overall cartridge dimensions. Most rounds made by CorBon and Buffalo we are told are made to SAAMI. Consult with the manufacturer to be certain.

My question to Henry -- "As this is a heavy round normally, and wanting to be able to reach out as much as possible, I am considering CorBon and Buffalo 45 LC rounds for hunting… those are acceptable rounds, pressure ‘wise, right?"
The answer from Henry -- ". Any of the 250gr selections from those companies will serve you well. The action has the same tensile strength as steel,so don't worry about the pressure. The only issue would be the length as some of the 300gr cartidges are really only possible to feed into a revolver's cylinder."
Thanks Les. Good info.
