Home Forums Hunting & Shooting Custom Rifles & Wildcats Ask Rick Bin Questions About the .338-.375 Campfire

been there too long; get ri of it

get rid of it; enough is enough; I have a 1907 autoloader 12 ga.
I will picture

I used to like the 30-06 and 338 because they shot about the same trajectory, albeit the 338 Win with another 50 grains, or a bit more.

I then came to prefer the greater distance of trajectory of the 270 and 300 Winchester magnum, the problem was what to do for a larger bullet? I never cared for the few 340 Weatherby rifles, which passed my hand, and this led to my necking up the 8mm Remington magnum, which is similar to the 340 Weatherby. I would think the necked down 375 Ruger to 338 would be even better.

I had some experience with the 404 Jeffery case and I know Dakota used it, I think it is also the bases for the ultra magnums; however, I have not looked to new ammunition in some years now. It seems the ruger would be a fine choice and I wonder why Ruger did not make the Alaskan in this calibre? It would shoot a little faster, have the trajectory of a 270 or a 300 Win with respective weight bullets; that would be nice, a 130-150 grain shooting rifle, a 180 to 200 grain rifle and a 225-250 grain rifle all shooting at close trajectory given the prospective relative weight.

For all practical purposes now, I would not need this but I still find it interesting

The title says ask ??'s

Do we get answers ?

Have owned .338win and .338rem ultra mag rifles along with .300rum and .30-378wby. Still own several .300win mag precision rifles and TRG-s in .340wby.

Most versatile round I have found is the .338/300win. Will just about duplicate the .340wby, but allows more flexibility of loading range. I use XMR 4350 powder and 250gr Sierra or Hornady bullets and load from 65gr (very mild ,about like .308 in a varmint special rig), to 78+gr which is is FIERCE, but not over-pressure.

This is a very longtime wildcat, but no load data around, so I extrapolated using 300 & 330 Dakota and 300 & 340 Weatherby data.

Have been a longrange and tactical enthusiast for over ten years, but cannot see value of going RUM, Lapua, or .378wby variant. For sure don't see the chey-tac or bmg ctgs as field viable.

About all I wish for is a non-belted case of .300win mag dimension, yet I ream my own barrels and therefore can set headspacing to the shoulder instead of belt and achieve almost same result. With minimum oal chamber case life is excellent, accuracy the same and moderate powder charges give longer barrel life.

Also have a cast bullet mold and intend to get around to casting some one of these days. Very easy to ream a .338win barrel to 338/300. Very easy to reload using 338 seater and .300win FL bushing die with custom bushing; or buy a wildcat die set.

Whenever I try and read the article on the homepage it links me to the 'Big Eyes' article.

Anyone help a guy out with a link to the article about the wildcat?

Anyone???

Bueller?... Bueller?... Bueller?

Well, The person who was working on the development of this round has not posted to this thread since April of 2008. Seems as though he has dropped the project and maybe decided to pull the article so poeple would let it go and stop asking about it. Sucks too because I have really been waiting for updates because this round sounds like exactly what I would like to carry for elk hunting. I use a 338-06 right now and it doesn't allow me to get the trajectory that I want from the bullets that I would like to shoot. I have a 338 Edge that is just too much gun (and far to heavy to carry around the mountains at 15 pounds, 3 ounces). The 338-375 sounds like it would fall dead in the middle performance wise and could be had in an 8ish pound rifle that wouldn't throw you into orbit when you pull the trigger.

what up with the 25 pronghorn ,or 25stw,ste some info thanks

Doesn't this round seem an aweful lot like the 8mm remington magnum that was basically born and went extinct on the same day.....? Oh, it is exactly the same aside from very slight bullet diameter :P

How does one access the article(s) mentioned at the beginning of the thread?

Who made the original reamer for this cartridge? I’m interested in doing something similar for a new deer rifle and would like to look at the reamer print for this.

Just reading through some old threads and found this one. My nephew shoots a 375-338 Chatfield taylor. Basically, a 338WM necked up. Decidedly deadly on big BC moose.

This thread could have some modern updates now that we have the 300 PRC. What would the best shoulder be and what would a recommend twist be for a 338 PRC?
