Does such a beast as a 33 Win "Improved" exist?

I'm not sure.

I owned a 33 Winchester in a custom Encore rifle barrel. I was getting 2,260 fps with the 200 grain Hornady flat points.

I'm sure a could have gotten a little more speed out of the old winchester round but the brass I was using was very thin.

Accuracy was great and I loved the old cartridge. But I sold the barrel and ordered a .338-08 from Virgin Valley. VVCG went out of business so I never got the barrel. (They did give me my money back).

At one time Virgin Valley had there own line of Wildcats bases on the 45-70, it was called the .338 VVC. It was sort of a 33 Win Imp.

It would make one heck of a lever action or single shot round.

I would like the dimention of the casings mercie

Ackley probably did one; try looking in his two volume set. There seems little doubt this has already been done, and were I you, I'd call RCBS to see if they have done the dies and call Clymer about the reamers. (I just tried the sites of CH-4D and JGS w/o luck.)

edited: The neck isn't terribly long on this case, so about all you can do is blow out the shoulder. Increasing the diameter from .443 to .483 will give you something over a 6 gn increase in case capacity, or about 10%. You can expect an increase in performance of about 3% for that, or about 65 fps with the 200 gn FP bullets -- hardly worth the effort, I'd say. (The .33 WCF is one of the examples in a case capacity calculator I wrote for the internet, and it is found here.)

Well, yes and no,

Winchester introduced the .348 Winchester originally to get slightly better ballistics than the .33 Winchester, with the same weight of bullet, in basically the same action (the '86/'71). Matter of fact, Winchester at first was going to call it just the ".34 winchester"

.348 is made on slighly different brass (.33 Win is based on .45-70 brass), but reportedly drives the same 200 gr. weight bullet just about 200 fps faster in actual chron'd loads.

You could do worse than just following Winchester's lead.....
