Can anyone tell me how much does the .375 Ruger case need to be shortened (with the shoulder moved back as well) so as to grip the 350 grain Woodleigh Protected Points (if they become available again) or the 350 Northfork SS in the cannelure when housed in a Ruger Hawkeye action such as the African? I'm only interested in running the 350's. I'm thinking 0.15" might do it. Thank you.
