In the 1875 catalog page 73 under “Improvements In Model of 1873” they list the velocity of the 66 at 1,125fps and the 73 at 1,325fps. T/R

They must of used a crude method of determining that in 1875, likely the breaking of two sets paper or strings set to timers at a certain distance apart. As per the Williamson book and other accounts, T.E. Addis while traveling in Europe purchased WRACo’s first Chronoscope in c.1886. Which I believe made WRACo one of the first companies in the U.S. to have one.

Thanks TR. I looked at that catalog but not close enough. I was hoping to get around 1100 fps.
By the way, it rained the day I last shot the gun. It sat in the rain for at least a half hour. I hope it doesn’t shrink. 
I cleaned the gun after the last 3 firings. It took over 30 passes through the barrel to get it cleaned. This is why I don’t usually shoot black powder.
It’s amusing as just the other day I was watching an episode of Wagon Train. It was season one, episode 18, “The Gabe Carswell Story.” There’s a lot of episodes of Wagon Train available on youtube but unfortunately I couldn’t find this one. Anyway, one of the stars of the show is a new Henry rifle that Flint McCullough had just acquired. He’s showing it to an Indian and they marvel over the fact that it can fire so many rounds – I think they said 15. Someone comments, “I’ve heard of these” – sort of like they just came out. Of course other members of the Wagon Train are shooting Model 1892 Winchesters. There is some throwing around of the rifle which seems a good way to put that fragile magazine tube out of service. Oh, the Indian does steal the rifle but Flint gets it back. Then, because the Indian is so emotionally taken with the rifle – and would be willing to die for it – Flint gives it to him. Then as Flint is walking away, the Indian is just about the shoot him with the rifle, but then the Indian’s father (a white man) shoots the Indian (who is his son) and we are left to assume Flint gets the rifle back. However, I don’t recall Flint having he Henry in subsequent episodes. Anyone else see this episode?
Shot the 66 today. I used a 205 grain bullet with 20.8 grains of FFFg for 1037 Fps. This is probably the max I’ll get out of this cartridge. I filled the case to the top then seated the bullet. I’m all out of bullets so I’m going to try to make some out of 44 WCF bullets that I’m going to try to squish to get them to .445″. If this doesn’t work I will be looking for more Henry ammo that someone has tried to shoot.

If you find some go ahead and clean the cases. Re-prime them using this https://22lrreloader.com/products/prime-all-repriming-compound and load them up. Let me know if it works.

Chuck,
I have a mold for the heeled bullet they used in those shells.

I’ve tried this compound but I can’t get it to go off in my cartridge. I recently annealed some of the original cases to soften them up but have not tried these out yet. I may need a new hammer spring?

How are you at making bullets? Seriously I have never poured my own bullets. This would be another project and expense for me.

Tom, my set of reproductions does not have this page? On page 17 it does talk about the 1873 going to the higher FPS. I was guessing I could get 1100 fps but the volume of my modified case really won’t take anymore powder. I really don’t want or need to work up a load using FFFFg. I looked at the coarseness of the Cartridge powder and it is more course than the FFFg.
Chuck, I think you are already on the cutting edge. My hats off to your courage. Tom

Chuck,If you want I can send you some bullets. I have some cast.
Bob
I would appreciate that if you have some to spare. Instead of mailing, how about bringing them to Tulsa?
Yesterday I took some .452″ bullets and ran them through a sizer to get .445″. I now have to cut the heal section.
