I've taken deer with 30-30 leverevolution bullets. Don't have any complaints. I've even started to reload them.
I have a one rifle zeroed just for this load, and the other ones I use regular bullets (Sierra, Hornady, & Speer).

A statement of fact: H&R Huntsman & Sidekick blued barrels are made of 4140 steel.
