FWIW-Probably not new info to most of you on this post-

In "WILCATS" by Simmons ('47)he has a small writeup on the .405-.308 Pope, stating that 2 target rifles and 1 hunting rifle were made up for it, and that Lucian Cary owned one of them.

Four pages later he shows the .30 Rimmed Magnum, a .405 necked to .30, made up by the legendary J. Bushnel(sp) Smith.

Good shooting.
