underwood ammo

has anyone had any experience with this ammo? how does it perform?
I am trying to find something cheaper than federal vital shok(barnes expander) for bear hunting with the same penetration.

I have no experience with them, but out of curiosity, why are you looking for cheaper shells to bear hunt with? I can’t imagine going through more than 1-3 shells on a hunt. Maybe it’s for the ability to target shoot with the same loads….anyways, someone way smarter than me will chime in.

I like to shoot a bunch with the ammo I use in the field.
I am using a .460 S&W 10.5 inch barrel. I like the federal vital shok tipped with a barnes expander, just looking to see if there is something with the same quality for less doe.
