Hi; I see 103 of you have read of my delima(10/29 post)of changing a M 30 Ex. from 3006 to 458 Lott but no recomendations. Am I crazy for pursuing this project or is it just too difficult a undertaking? I've spoken to a Mr Williams in OR. a contemporary of Roy Patterson. who said that this was a relative simple process but that he didn't do it any more because of age and it used to be done alot with the modifying of the 1917 Enfields and the M30's and Roy had addressed this in his book of gunsmithing. which I referenced. but to no avail. Mr Williams said that the rails could be trimmed .020 and the follower shortened and the box would then accomodate the banded case and flat nosed slugs w/o further magazine modification. I've repeated this to a few recommended smiths and they shake their heads and roll their eyes and tell me that the process is more than that and they can't or won't help. Anyone out there with an idea?
