CheechakoWell dang it Roger, I was standing by waiting to see the results.
Your little Gremlins gave it away.
But, you know what, I'll bet you'll get guys to thinking, hmmmmm, 8mm/50BMG, maybe that would work.

It sure would let us use up a bunch of cheap 5010 and 5020!

Tyler KempMake it 338 to use the 300 and 350 grainers with insano BC's!
Love shooting precision and long range. Big bores too!

300 grain capacity and a 8mm bore damn bart that really sounds fun!

I think you are right and look it only took you 27 days.
I think prior to WW II the poles came up with a similar anti tank rifle. Either it didn't work very good or they didn't have enough of them!

homebrewerHow about necking a .375 or .400 into that BMG case?
You know what I think? I think the fox among all them dogs is there for the pre-hunt safety briefing...

It's been done. State Arms used to offer a rifle chambered in that round, called it the
Mach V. Here is a comparative pic of the
.375/50BMG round. Jacketed lead in .375 could be sent down the tube @3700 fps. Barnes copper solids @4400fps and Klaus sold bronze solids that would withstand 5200+fps!
Since the previous owner, Klaus Horstkamp, was killed in a truck rollover, State Arms was bought out by an employee and renamed East Ridge Gun Company. The Mach V is no longer listed on their website, but I'm sure they still have the reamer.

Tyler KempWhat would barrel life be like? Anywhere similar to something like a 204 or 220 Swift?
Or more extreme yet?

I have no personal experience here, and not many Mach Vs were sold, so there's not much out there about them, but I'm guessing barrel life would be similar to a .220 Swift...back in the '30s. Maybe worse.

You could do a case capacity to bore ratio on both comparison and come up with a pretty educated guess.

You would need to come up with 3 guesses. One for the jacketed (Sierras?), one for the Barnes bullets, another for those bronze bullets. The jacketed and copper bullets just can't hold up to the rpm of a fully stoked load. There would most likely be a
big difference in the rate of erosion, from one load to another. I have an internal/external ballistic program that will calculate expansion ratios, I could figure in the dimensions of a .50 BMG case necked down to .375 and even come up with some loads, if there is a slow enough powder in the database.
Ahh, maybe one rainy day.

Is 5010 or 5020 in your data base?

MacifejHey guys did I mention that y'all boys are reinventing the square wheel again??
The cartridge already exists and is in use. It's on Ammoguide, Pac-Nor does the chamber and barrel, etc., etc.,......about the only thingthat hasn't been done on the BMG case is a 10 Bore short auto pistol.

AtkinsonI knew you were kidding, you have a 50 BMG necked down to a phonograph needle, but thats just between us, none of these baby boomers know what a phonograph needle is!
