This past weekend I inherited a beautiful rifle, and I was hoping that someone here might be able to help me with some information on it. I have searched the web over the years multiple times and this has repeatedly been the only site that I have found with any information on the subject. So the rifle I inherited was built by my great grandfather for my grandpa in 1961 or 62 I think. The rounds that my great grandfather made for it that I have were loaded in 1963(I shot 2 of them today). My great grandfather wrote .300 Ackley #2 on the box of ammunition he loaded, so I assume that this is the Caliber of the gun. The dies are long gone missing, and there is no one in my area that I trust to mold(can't think of the proper name) the chamber. I have the Ackley book, but I only have Volume 2 and there is nothing that matches what I have. Once upon a time my dad purchased some 30/338 wildcat on a wild hair thinking it was the chambering of the gun. Although the 30/338 is close, it is not a 30/338(at least the one he had loaded). The rounds I'm looking at use 308 Norma and 338 win mag as a parent cartridge, but I can tell that the neck has been lengthened and the shoulders are much further down the shell. I know that at one time the shells were fire formed. I was hoping someone had some more information on the .300 Ackley #2 because I would like to be able to load rounds for it, but I have not been able to find any information on this particular chambering anywhere. Any help would be much appreciated.
