Id say maybe for the biggest toughest game... but a barnes in that bullet size is gona take a lot to expand...
I like them in everything under a .308
that was the other question I had for Barnes. They said there is no problem expanding with 45-70 speeds. Bullet is designed for bolt gun or single shot like the Ruger #1.
Wonder how they run in a .450 Bushmaster or .458 SOCOM
I was specifically looking at the 400 gr bullets. Barnes book shows 300gr and 330gr for the Socom.
Speeds run 1600 to just over 1800FPS. I would assume expansion would be ok at these speeds but no experience.
I ask cause I have barnes fail to expand in 308 and in 3006. I know others have had issues as well.
