I made a little spare time today and went out back to try out my new teppo, or Tanegashima. It is a repro of a Japanese cheek stock matchlock with a 50 caliber 42" octagonal smoothbore barrel. Made by Miroku in Japan, apparently. Mine is serial number 65. I bought it second hand but unfired. It has browning inside the barrel.
It's a weird and interesting firearm. The stock ends in a blocky pistol grip. It has a slender brass arm with a 5/16" rounded trough in the end for the match. Lift up the arm and a little steel pin pops out of the lock face and holds it up against a weak spring. Pull the trigger and it drops onto the pan.
The sights are roughly 1/2" cubes. The rear has a small V notch. The front has a small hole drilled through it front to back with a slot cut down to the hole. Kind of like those open top peep rear sights people make. I'm thinking that I should paint the inside of that hole with something reflective to make a glowing dot.
The vent hole goes in and down from the pan at a 45 degree angle.
The ramrod channel is a ramrod hole with a slit, all the way from the muzzle. No thimbles.
I made up four paper cartridge squib loads of 60 gr FF and stuffed some 490 balls in lubed ticking in my block, grabbed a length of match and went out.
It loaded hard. The muzzle chamfer wasn't rounded (it will be) and the bore seemed to be as browned as the outside of the barrel. I primed it with 4F, closed the pan cover, and squashed the oversized match in the serpentine trough. I had to pin it in place with a piece of wire.
Opened the pan, put the stock against my cheek,said "Jozai Senjo" and pressed.
Clunk. Nothing.
Match out, reprime, close cover, blow on match, squash and pin match, open pan, pull, flash in the pan. @!*%. Went around again and decided to hold it out away from me so I could see what was going on. It went off like a champ. Not much kick with the heavy barrel.
I fired three more shots, the last of which came in 1" low from dead center at 25 yards. The other two were kind of random, a few inches off one way or another.The ignition is a bit slow for a matchlock, probably because of the long vent hole. No way to put a vent liner in, though.
I could see firing this with powder loads up into the 70s without discomfort. I need smaller match. I'm also thinking of enlarging the very small pan recess, although from photos I've seen the Japanese pans tend to be small. The reflective lining for the front sight is a must, as is the muzzle chamfer. The interior browning should wear off.
It could be difficult competing with this because it is essentially a Japanese smooth rifle with a very prominent rear sight. The front sight is too tall to be used without the rear. I don't want to replace them because they are right for it and look right for it. I want to take it to the primitive biathlons, so I may have to decide between authenticity and competing against actual rifles.
I don't have any good photos of mine yet, so here's a generic photo of it from a catalog:
