Rod,

Great info. I'm dreadfully uninformed as to the .303 and enjoyed reading your posts.

As a general matter I would caution against loading .315" bullets in the Ruger until the shooter has determined for certain that there is sufficient clearance in the chamber neck to accommodate the larger bullet. I know you agree with this and that you are well familiar with what I'm saying. My statement is for those who have less loading experience.
