If I/we could talk you into 6, it would be very interesting to see pairs of cartridges. 25-20 with 32/20, same basic case and capacity different bore. With what you listed there are 3 pairs.
 
To narrow that down to four, it would be 25-20, 32-20, 32 special, 38-55. Same reasoning but also small case capacity, large case capacity.

That might give some hints to bore size, pressure build relationship.

2 more won't matter. What 2 do you want. I've been reloading for 65 years, owned chronographs for 60 &  been pressure testing for 22 years (over 15000 rounds). To answer the Ducati question I've owned 250, 350 & 450 desmo singles, the first year 750 desmo twin & currently a 944 desmo twin that I road raced from age 52 to 60.

The 25/20 WCF could be used as a reference for the 25/20 SS as the WCF only holds 1g less. I have a soft spot for 25 cal. rifles as I own 9. I raced in WERA & CCS, Heavy Weight Sportsman & Formula 40 & 1 time in Superbike. Last race 2005.

You had a Scott?  It was either well preserved......or you are! 

A quintessential .25 black powder cartridge would be the .25-20 Stevens.  If a barrel had to be made, I've got the reamer.  Also one for the .25 Stevens rimfire. 

I had already decided to do the whole lot, i.e., 25/20, 32/20, 32 spcl, 38/55, 33 wcf, 38/56, 38/40 & 44/40. As I said I had only done the 45/70 with black for a friend. Thought it would be interesting to know how other calibres worked. Will post results as soon as get them tested. I'm also amazed you had a Scott. I've only seen them in a museum. No I don't have a 25 Hornet. I have a 25/20wcf, 25/20ss, 25/25, 25/35, 250 Savage, (2) 257 Roberts, 25/06 & 256 winchester (ruger hawkeye).

Howdy fellas!

I ran across this forum the other day when it popped up on my search engine results.

I did do a lot of testing the 44-40 for pressure results. I wish I could do more but with the cost of everything going up and me being a bit computer stupid, I called it quits a while back. 

I gave the PTII to a fellow tester who also has the Oelher equipment. He did send it back to me once so I could do 
some additional misc testing I wanted to do with older "bulk for bulk" powders. 

What I would like to do is to load the 44-40 and test for velocity using different powders to maintain 1,325fps. That test would give a better understanding as to what powders create higher pressures, or create pressure spikes, in order to maintain 1,325fps velocities.

I know the website is a mess but it is a free site so the options are limited. Combined with my lack of skills, it can be a mess.

Anyhow, if I can help in any way, just holler at me.

I could use the help of viewers to give some feedback on the website's layout. I tried to get some sort of order going but it just isnt that easy.

Before John Kort passed away, he gave me permission to post all of his information onto the website. That too is not easy.

The 44-40 subject is a bit hidden in general because there is not a dedicated place for such a cartridge...well there is now if folks care to trickle in and get it started. I feel some m y better visit a forum than the website.

The website just shows how much 44-40 data is really out there, I too get lost looking for something I posted, not know exactly where it got placed.
