You will need 4 custom dies to form the brass and two custom reamers for the chamber and loading dies.I don’t know what this alternative cartridge is, I cannot find it on the web. I’m not getting any specs on it - and the pictures, while pretty, still are not informative about dimensions. ..and my curiosity is piqued.
So, still waiting for answers to my actual question. I am being given alternatives, but no symmetrical responses. Also, not sure where the 340 entered the discussion.
So, to sum up: If you want to offer an alternative, please give me its dimensions and specs or where I can learn about it on web.
And, if there is someone who has background on MY project , the wide 338, I’d love to hear about making the brass up. (can I just resize it and move the shoulder back that far?)
Barrels are another thing for a later time.
