I have recently acquired what I believe may be a genuine military-issue 11.63 x 33mm belted cartridge (AKA 458 x 1.5" Barnes) and would like some help in verifying (or disproving) its authenticity. I read an older post in the forum archives that sheds some light on the subject and it appears that it matches the information given there. It has a case length of 33mm (1.30") and the headstamp is W-W SUPER 458 WIN MAG. The bullet is a 500 gr. FMJ roundnose. I bought it at auction from the estate of a collector who most likely acquired it from Aberdeen Proving Grounds, but there was little other helpful information that came with the round.
Does anyone have a copy of the article about this cartridge in the IAA Journal #444, p.125 that you could send me? Also, I understand that Woodin Labs was involved in the development of this cartridge. Does anyone have contact information for Bill Woodin? While I’m not planning to sell it, I’m curious to know what it would be worth if it is genuine, as it is apparently a rather scarce item. Any guesses? If anyone has this cartridge in their own collection or knows more about it than is in COTW, I would love to hear from you. Thanks!
