.338-74 Keith

Elmer was one of my favorites, I still read everything of his I can find. He liked the .33 cals. and I remember his stories about necking the 9.3-74 down to .33 for single-shots. 4" long IIRC. Anybody here have any experience with this? A friend will sell me a #1 action cheap and if I get it I think it would be an interesting project. Ol' Elmer seemed to think it was the cats meow. It'd sure be different. :cool:

No actual experience, but I love Keith's writings, also. He started with .333 bullets from Britain as USA did not make them back then, IIRC. The 338 Win and 340 Weatherby are direct descendants of Keith's research with his various .33 wildcats. He was also a BIG double rifle fan and that's where things like the rimmed 9.3X74 wildcat stepped in. Similar to 338 Win in performance (again) IIRC. Bravo, sir, for keeping the flame burning!

Love to Read Keith myself.. Thinking of trying some of his 44 spl load here soon and would sure like to try this wildcat maybe one day

Yup, Keith was GOOD. .338-06. Naw, .333 O.K.H.
What did O.K.H. stand for? ;)

From the reload bench;

The 333 OKH was developed by Charles O'Neil, Elmer Keith, and Don Hopkins in 1945. It is the 30-06 case necked up to accept .333 inch diameter bullets. At the time the cartridge was developed, .338 inch diameter bullets were not generally available, but .333 inch bullets were. When the 338 Winchester Magnum was introduced in 1958, a wide variety of 338 bullets became available which led to rifles being made for the 338-06 cartridge. The difference between the 333 OKH and the 338-06 is miniscule and one can use loading data interchangeably. However, the two bullet diameters are not interchangeable.

Conjointly with the .333 OKH the three also produced the .334 OKH, based on the .375 Magnum case. This resulted from a disagreement as to the optimum case volume for the bullets, Keith favoring the maggie based .334. He did not turn his nose up against the .333 but he still was after more performance. Read GunNotes Vol 1 and 2 for lots of stuff about ole Elmer's empirical experiments and real world results. You will probably no longer read Fackler/M&S/Whoever. JMTC

I wish it was called .338 OKH. Just to keep Keith on it. .338-06 forgets who made it.

True. The 334 OKH turned out to be the 340 Weatherby, without the fancy shoulder.

Hey M99M12! Heck, just get a .338/06 made and dub it yourself. That's the way the .35 Whelen came about. Col. Whelen had nuttin to do with it; it was named in his HONOR. Best!
