Here`s a pic with the TrailBoss. The Munich Proofhouse has tested the load and the result is ,that the load is absolutely o.K. The gaspressure is only 40bar over the BP-load and the speed difference is 2m/s in a 5 shot average.

Hello Gunner,
I have been using 16 grains of Trail Boss to drive a 340 grain hard cast bullet in my 71/84. What are the details of the Trail Boss load that you had tested as quoted above? What weight of bullet and powder was used? Did you use any filler between the powder and bullet?
It too me quite some time to establish this load, so if you work up a satisfactory load with BP for the 350 gn bullet I would be grateful if you would post it here, to save me some work! My estimate is that, with the shorter bullet, about 75 gn will fill the space without compression. That combination should produce a significantly higher muzzle velocity, and may well perform better at 100 meters, than my load, which is intended for long-range shooting.
So much for theory. I tried this out on Saturday. The original load performed better.
Over the New Year´s Eve celebratory fireworks event here in Berlin, I took the opportunity to shoot both my short Werder and M71 cavalry carbines with identical BP and substitute (777) loads and measure the Vo. Apart from blasting a hole in the back wall of my work shop, I found that the BP substitute was much too fast and that the recoil put noticeable stress on both weapons. In comparison, it was more than clear that the substitute BP would most likely cause damage over even a shorter period, whereas BP was much milder and came quite close to the original specifications.
I realise that BP is a lot messier to shoot (the dust in a closed space had to be seen to be believed) and a bit more complicated to re-load. But there seems to be no alternative. Think I´ll experiment with re-loading the rest of my 777 for my LE No. 5.

Sorry for the late reply, i had some days off. The bullet is a downsized 300grs. KSHS .451 bullet from Haendler&Natermann, the OAL is 74mm, but the exactly load that was developed by a friend is his secret, for now. I´ll ask him if he would tell it to me and post it as soon as i got it.
Hello, Patrick,
The cat is the top part of the family arms registered in Hessen. The Romans referred to Hessen as the land of the Chatten. Ancestors were teachers and magistrates.
I'm working on a Bubba 71/84: 8" off barrel and wood shortened at both ends. Very sad. Rifling looks excellent. I think I can build the parts necessary to convert it to a 3-shot repeater. I have my own 71/84 to use as a pattern for parts. It gets me out to the shop.
The Romans referred to Hessen as the land of the Chatten.
In the 1st century AD, the Chatten/Chatti were a tribe living between the rivers Fulda and Werra. At one time they had a spot of bother with the Cheruscans about bride-stealing (the Cheruscans were the tribe of Arminius, a.k.a. "Hermann the German") and like them were regarded by the Romans as awkward customers. Somewhen around 83 A.D, after getting on the Romans' nerves too badly for too long, they were attacked by the Romans under Domitian (I guess he had to justify a triumph) and large numbers fled down the Rhine to Batavia - now Holland.
There are two place-names in Holland - Katwijk an der Maas, just south of Nijmegen, and Katwijk an See, up the coast from Den Haag. The soft chat... has hardened to kat... in German and Dutch, and of course ...wijk is the same as English ...wick, meaning a settlement or village.
So Kat...wijk is equivalent to Chat...wick.
It looks like some of the Chatti stopped in Nijmegen, and others carried on to the North Sea coast.
But the really adventurous (or desperate - who knows?) Chatti got on the boat, and sailed off to Britannia. And at W 1°42'10.8" / N52°21'17.28" you can find the hamlet of Chadwick End. Sounds like a place where the Hobbits used to live!
It took some time before the former Chatti made it to the New World, but they did eventually reach Boston, where the former main building of the Chadwick Lead Works is a preserved building. And in the Civil War, "K" company of the 1st Massachusetts was a Zouave unit formed as the "Chadwick Light Infantry".
All of this light-hearted history only goes to show that people move around a lot, if you give them a couple of thousand years!
But I would guess that the family name associated with the cool cat is probably something with Kat... or Katt... Am I right?

Very good idea! Maybe more than 3 shots? If you look in Ball "Mauser Military Rifles of the World" you will find pics of a Model M71 Short Rifle, which might be helpful.
