    Guys I need some help....

    I had a rifle fall in my lap from a friend... Father-in-law passed away and was an avid collector...

    This is a Ruger M77 rebarreled into 7x57mm Graves Improved Tight Neck. I have a couple pieces of brass and they look like an Ackley Improved but the barrel is stamped Graves Improved Tight Neck.

    Has anyone heard of this caliber or have any info on it?

    Thanks in advance!
    Brandon

    Never heard of it. You need to do a chamber cast to get accurate dimensions. It may be an Ackley with the neck on the small side for use with neck turned brass. A cast of the chamber can confirm what is needed for making reloads.
