.357mag HC= Cor-bon or Gray Area(WeShoot2)
.44mag HC= Cor-bon, Garrett, Federal(yes, I like them), Gray Area, Buffalo Bore.
Federal 300gr HC is probably the cheapest @ 19.95 for 20, but I like the results I have had with it. I am not sure how the bullets will hold up in bone, haven't shot anything with them yet.
You get what you pay for and the small companies are worth the extra few bucks. Practice with cheap stuff, hunt with the best.
