Chuck-

You’re certainly making me appreciate my relatively standard cartridges and cheap Lee Zip Trim and trimming tools. That long case presents quite a challenge!

Good point. I cranked out some practice fodder on a Dillon 550 for my social equipment this afternoon. Very efficient but rather mind-numbing.

Agreed- I made up a few 9mm pinfire cartridges for a Family heirloom piece a few months ago.  Tedious but rewarding

Ron, now that sounds very interesting. 

I was able to shoot my 38 EX rounds today before the rain hit us.  Used the largest diameter bullets I have.  Had to force 5 of the 6 into the chamber.  After firing they all ejected fine.  Somebody have some .382″?

Shot the 6 cartridges yesterday.  This is the second time with the .381″ bullets. It is probably the last time I will use black powder.  My next loads will be with 4198. 

I’m still having problems loading these rounds.  The seated neck diameter is too large.  Being a shooter I want to do what is best for accuracy but I really don’t need to be accurate.  I am contemplating inside neck reaming to thin the brass about .002″.  I have a neck lathe but it is for cases with a shoulder to cut up against.  The cutter has an edge that is the same angle as the shoulder. These cases don’t have a shoulder so I don’t want to leave a ledge where it might crack.   Doing it on the inside will leave no shoulder because the brass gets larger and the cutter has no brass to cut. 

Open the link and look at the pictures below the tool.  You can see the profile of the cutter head.   Most run between a 25 to 40 degree angle on the one edge.

Just talking out loud… What if you use a smaller diameter bullet but paper patch it?

That might work.  I have never patched a bullet but my friends that target shoot black powder do all the time.  The next smaller bullets that I have are .375″ diameter.  The .380″ bullets when seated won’t chamber easily.   I should call Bear Creek and see what they can do.  I have a lot of .380″ and .381″ bullets.  I might talk to Lee Precision about one of their dies that can squeeze the bullets to whatever size I want.  I have said this before.  I do this to 45 ACP bullets to get the .443″ for the Henry and 66 rounds. 

I don’t have a die to size the cases or crimp the bullets, But I doubt it would help.

Chuck,

A simple bullet swage tool/die will allow you to reduce your bullets from .381 to .379 (or the diameter you need).  I have a small supply of .379 bullets on hand, but I use them for my 38-55 high-wall.

You should not need to crimp the bullets for a Single Shot rifle.  Resizing the case should be limited to just the short area where the bullet seats in the case.

I don’t think any Winchester ammo needs to be crimped.  Get the needed neck tension and your bullets will stay put.  I was thinking of crimping these because the mouth of the cases stick out some. 

Here is a picture of the Lee Breech Lock Bullet Sizer that I have.  I would have to order the bottom 2 parts.  A correct diameter sizer and the punch.  I messed up and the sizer is upside down but if you look closely it reads .445.  When using this tool you have to remove the bushing on the RCBS press so you can use the large diameter threads.

A .379″ bullet of 20-1 or softer alloy is what I believe you need. That is likely what a factory load of that time would have had. I don’t know if 4198 will bump up the softer bullet to fill the bore as well as BP but I’ll be finding out soon. I suspect paper patching will actually make your chamber issues worse as paper patch chambers were generally cut a bit larger but I’ve never wanted to try paper patching. I recommend trying to find a template and recommendations on paper thickness. I never had the patience or old school digital dexterity to try it.

Mike, that is what I’ve been thinking, .379″.  It would be .001″ smaller than the bore but I might have to live with it.  Once I get the cases to chamber easily I might hollow out the bottom of a few bullets and see if this shoots any better.  On Tuesday I can talk to the guys that paper patch bullets all the time.

But, this rifle is not going to be used as a target or hunting rifle.  I have already shot more rounds than I ever thought I would.  Now I’m really looking out for a 40 EX and the 50 EX.  I’ve seen 40’s before but never a 50.  At least one that was real. 

Certain old documents say there was only 1ea. 50-140 made but that is not true.  I have a copy of the Ledger page of the 45 EX I own and it shows at least 10 ea. 50 Ex. rifles.  The 50 EX for the 1876 are listed as 50-95’s.  Vol 1 page 9 of Shuey’s Head stamp book under “The Enigma of Winchester Cartridges not Listed in Catalogs” he states ” Another is the 50-140 Express.  One Winchester Single Shot rifle is known to exist in this caliber along with a number of loaded rounds and factory new primed cases.”  In Vol 2 on page 180 he states that Winchester single shot rifles are known to exist in this caliber (50-140 EX).

I already have some brass that I could use to make these cases. Both should be easier than the 38 EX.  The 38 EX is the only one of the 4 that requires the case to be squeezed down to get it into the chamber for fire forming.

Chuck,

The “50 Ex” cartridge notation in the early ledger records almost always referred to the 50-95 WCF cartridge, not the 50-140.  For the two rifles that were actually factory chambered for the 50-140 cartridge, both were entered in the ledger record as “50 – 3¼“.  In the later ledger entries, the notation “50 Ex” was frequently used for the 50-110 Ex cartridge and the 50-95 WCF cartridge was entered as “50-95”.

Thanks, so how many 50-140’s do you think/know were made, 2?  I need to go through my notes because one other person said there was only one. 

I have a board dummy and 1 loaded round and those may be all I ever have. 

Do you have an idea how many were made in the other 3 calibers?  Over the years I have only seen a few 38’s and 40’s. The 45 I have is the first one I’ve ever seen for sale.

Chuck,

I positively know that just two rifles were made in that cartridge, serial numbers 63042 and 66362.  I suggest that you read my article in the Winter 2021 Collector magazine found here – Winter 2021 (winchestercollector.org) as it will definitely answer all of your questions.

To illustrate the inconsistencies that are found within the factory ledger pages, see the attached copy of the ledger page for Single Shot serial numbers 12300 – 12325.  Take Note that there are (4) serial numbers that I have hi-lighted.  All four rifles were received in the warehouse on the same date and then shipped on the same date to Order number – 24881.  Three of the rifles are annotated “50 Ex” and one is annotated “50-95”, but all four are in fact chambered and marked for the 50-95 W.C.F. cartridge.

I have personally had my hands on 3 of the 4 rifles, and all of them are in fact 50-95 WCF (I serial number 12302 in my collection).  All four rifles were exported to Australia (James Rosier) and bear his “J.R.” marking on the barrel.  The other two rifles were purchased by well-known Winchester collectors/dealers here in the U.S.

Thanks, didn’t remember the article.  Back then I never thought I’d own a EX of any caliber.

Honestly I forgot the 50-110’s when I made my guestimate.

I loaded the 38 EX rounds with 23 grains of 4198.  I am testing the filler quantity to see if I get more pressure with more filler, or not.  I’m hoping that a small amount of filler that fits tightly against the power will work.  These rounds can finally be chronographed.  I want to get somewhere between 1400 and 1500 fps.

I suspect that you will find that 23 grains is going to be a very light load and well short of 1,400 fps.  I load 38-55 cartridges with 22 grains of IMR 4198 under a 255 grain bullet, and it produces 1,500 fps in my high-wall 30″ barrel.
