Good to read from you Mister Kayser. I’m a former subscriber of PS, as many of us are, and I really appreciated your writings. Any news from Bob Jourdan and Dave Brennan?

Take care,

BHO

b Bertram,

that is an excuse. As long as people cannot buy brass/loaded ammunition any claims the originator wants to make are just noise.

In 1992, I was a staff writer for Precision Shooting Magazine. I developed a cartridge called the 338 Gryphon. It shot the SMK 300gr 338 bullet about 3650fps from a 34″ barrel.
We used the 50 Spotter case. It had the same issues, extremely short barrel life, and non-availability of brass.

I also had a 223 Eargesplitten Loudenboomer made up in 2000. 378 Wby necked down to 22 caliber in an AI version. Shot the 60gr Nosler Solid Base bullets over 5400fps. The problem was the 80 rounds per barrel life. It was written up for PS and appeared in the magazine.

Ed Hubel has several thousand rounds of his 585 Hubel case for sale today.

Stick with things you can actually buy…

The brass problem is actually a BATF requirement that the importer get an import licence.. and for the small quantites talking about no one thinks its worth doing..

I think the easy answer, given the benefit of hindsight, and taking into account real world testing, cost and availability is … “no”.

The .375s are the current darlings of the long range set and more work needs to go into them. 30 cal, like 7mm, suffers from the effects of Newtonian physics beyond a certain distance.

Always remember, the envelope is there to be pushed.

I think it’s worth mentioning how short barrel life would be when we mention awesome calibers like these. That way a newbie can forget about it right away or at least know what he’s getting into.

Butch is correct, the cartridge was the .375 Lethal Magnum (http://www.lethalprecisionarms.com/indefinita.html).

Before you conclude that this is something new, this article was first published 24-Mar-2012, then re-published 16-Nov-2013. The lead paragraph in the 2016 re-publish is an addition.

Minor correction, the base case is not an Allen .338 Excalibur but an A-Square .338 Excalibur (http://www.broadswordgroup.com/338_excalibur.html)

I have a .338 Allen Xpress (+P variant) that pushes 300 gr Bergers to 3244 from a 36″ barrel without significant pressure signs, other some level of an ejector bounce mark on most fired cases.

My main grief with anything Allen, other than unbelievably long lead times and virtually zero communication until you actually come up in queue) is that the Allen cartridges are all proprietary – no reamers for sale. So you buy multiple chambered barrels up front,

BTW, the Allen Raptor page currently leads with, “Because of issues with the brass manufacturer the 300 and 338 Raptor unavailable for order at this time. IF the brass situation changes in the future I will let it be known to the public but for the time being, sadly, the Raptor wildcats are unavailable for order.” (http://www.apsrifles.com/Raptor_Wildcats.html)

How about the King of Two Mile rifle report. Believe it was won with a 400 grain Berger in a necked down 586HE case.
