30-378 Weatherby

[SouthernCoyote]

Bringing an old thread back up, do any of you have and experience with Swift Sirocco II 180 grain projectiles in the 30-378? Fixing to start loading for it for long range Elk, Grizzly, etc. Was curious as to how the Swifts do in such extreme velocities like this caliber?

Using it for grizzly I would avoid the Sirocco. It's not really designed for penetration. Swift A-frame would be a great choice but your sacrificing BC

Barnes TSX or TTSX may be a good compromise
