Underwood just announced their new xtreme penetrator ammo in .45-70. Pretty hot 305 grain copper solids. Curious about opinions on it. I like their ammo in both rifle and hadgun. It is clean, reliable, uses good components, and made in the U.S.A. I don't have any relationship with them, so I'm not trying to promote their products. What do you all think? Here's the link to it: https://www.underwoodammo.com/45-70-government/.
