Clive – I didn't think they called in the black powder vintage hand guns?

When this thread started, I thought here we go, someonesgoing to say STOP, you can't talk about this, its naughty, worse than porn, but I was happy to see that those ones have stayed away because this is quite interesting, specially the link to the Scottish Pistols. Ian S C

Hi Steve, the only Black Powder gun I had was a Beretta O/U shotgun, when I took it to the skeet range everybody wanted a go and it used up all my powder very quickly. It smashed the clays every time but was slow to reload and made lots of smoke.I did for a while use Pyrodex powder, a Black Powder substitue but again it was expensive. It was also very good on Pheasants, patterning very well and the dog did not like the boom instead of the bang of a cartridge gun.

Your right that they did not call in the B/P guns but the following was very low, now they use cut short rifle type guns with pistol grips to get around the pistol ban.

Jon you are right about hammer forging. I believe Mannlicher leave the rather pronounced spiral on – possibly as a trademark. Watching machine gun barrels beign hammer forged at Enfield, again that took what, less than a minute.

Clive one of the advantages of decent quality black powder is its consistency. Its actually a more consistent propellant than smokeless, and its a lot easier ot set it alight consistently. As a consequence a lot of black powder ammo is very consistent indeed. The problem comes with the business of spin – the generally longer bullets are highly spun for stability, and because of the lower velocities the launch angle or line of departure is realativley steep. Combine htat with being heavily overspun for stability downrange and hte thing locks gyroscopically at a rather awkward angle upward angle relative to the trajectory which is tedious. Tends to fly nose up generating slender body lift as a result of the crossflow, and all sorts. So its not the ancient propellant at all which is darned good – its actually the physics of older lower velocity ammunition whihc tended to limit performance.
