Still a member here, I'm the OP in this thread. I've posted the rifle on a few forums, but no one else has any information on it. I did a quick search, found this thread and gave it a bump to see if any other information has come out about these type of rifles. I mainly collect US military sniper rifles, and I've been sharing new research and information on the M40 series for many years. I've also been able to find a lot new information on M40's going back to 1966, so it's not a stretch to assume that more information could have come out on this type of Weatherby target rifle in the past decade.
I also wanted to repost photos of this rifle that are now missing in the OP. As far as I can tell, these are the only photos of a Round Nose Weatherby rifle online, so some people might be interested in seeing them.
There's tons of ways that new information could have surfaced in the past 10 years. Photos, auction/sales links, early Weatherby brochures, other forum threads, etc. I wish I could find information on this specific rifle, but I know that's a shot in the dark. Aside from the rifle I own, I'd love to see any information on other rifles of this type. According to some people, this isn't the only rifle of this type known. If that's the case, are there photos of any other rifles? What caliber are they? Were they built for a specific shooting event or just bench rest in general? Any new photos/information would be extremely helpful.
I appreciate the guys who have provided information about these rifles, and who have also reiterated that information in the past few days. Thank you everyone who has provided information in this thread! I'm hoping that more photos and information on other similar rifles will eventually be found. I'll keep checking on this thread to see if anything new is posted.
