I'm not sure I'll load the Ruger up to full factory spec's. The rifle I forsaw was lightweight, American made, and is as capable as the 375 HH.

Caution will be needed as most 375 bullets are made for the HH, not Ruger speeds.

I think Triple X, Northfork and Woodleigh will be the way to go for speed.

Bad bullets is what killed the 10.75x68 in Africa many years ago...................JJ

By Barnes and load at what ever speed the chamber will handle As long as it is still accurate
