Tenspot, you probably are correct on the dates. Won't even consider questioning it. My intro to the short, fat, efficient cartridges (aka 6PPC) came just a little later, and has since been a matter of much contemplation on my part. I, do, however, stick with my analysis that the old 300 WinMag does a great job. Brass is now not as big a problem for the SAUM and wsm as a few years ago, but the SAUM still devours powder, makes action requirements longer and heavier, and maybe consumes barrels(I don't have any evidence of this, but think it's probably true). I'll also admit to never being a fan of the Wby Mags(too long). Bottom line---- the wsm may be the best of all possible worlds, but I'm pretty happy with the original--the 300 WinMag(until my pocket book regroups to get a wsm)
Regards,
Dennis
