old McMillan needs identity

[jimisbell]

I have just aquired a 50 bmg identified as being from McBros. here is a pictere of it. I am having no luck in tracing its origions. Jim Schmidt at Arizona Amunition tried but didnt come up with anything solid. the action is marked McBros, the brake is a mystery, the barrel is reportedly a Walther 36" 1-15. It is a single shot "shell holder" action. It came with a custom sizing die made for this chamber and lots (250 pounds) of extras including powder, primers, brass and full set of loading tools. I am trying to trace its history and origions to decide if it is worth restoring and tuning it. Supposedly less than 100 rounds thru the barrel. Any help in tracing its history would be appreciated.

There was a guy in Houston making .50’s back in the early 1990s. He got an article in the Houston Chronicle that I read in the paper… so must have been 1992-1994 timeframe.

Though that looks different. Then again… almost 30 years!

Nice looking rifle!

The McBros 50 BMG Action - Lilja

To those not familiar with the 50 caliber BMG round, their first impression upon seeing a loaded round is; hey, that thing is BIG. Indeed, a 50 caliber round is big, even compared to our largest magnum rounds. And so it is with the McBros 50 BMG bolt action, designed for shoulder fired, sporting...

Thank you. that article was very comforting to me, the guy with his face on the line.
the seller told me he thought the gun was made in 2004.

The range report will have to wait till weather cools down in the west texas desert. AND until recover from my broken shoulder from a fall last week. Thank God it was my left shoulder and I am right handed. But its the most painfull thing I have ever endured in 85 years.

Wow.
That is different from any .50 I've seen.
If it shoots as good as it looks, it'll be fantastic.
Nice score.

Klaus Horstcamp used to say (in a thick German accent) they are "zupa accurate".
I hope the OP follows up with a range report.
