Hi,
I'm a new member of this very interesting and informative forum living in the United Kingdom.
I have a Ruger Old Army which has been converted to use nitro powder and shotgun primers. I was advised to use 4.5 grns of Herco behind an Alox lubricated .457 round ball.
When this load works consistently it sounds right and is very accurate, but I'm getting quite a few weak discharges and have noticed unburnt powder accumulating in front of the muzzle.
I would have thought either the ball is not seating tightly enough or the powder is not burning fast enough. As already stated, the ball is the recommended .457 dia and I can see a ring ring of Alox coming of after seating, but not really a lead ring as with my BP revolvers. I have also tried ball from different makers with no difference in the results obtained. I realise that it's important to use a 'Flake' type shotgun type powder in these conversions to prevent finer powder disappearing through the primer hole, but wondered if a slightly faster burning powder than Herco such as Unique might help the situation.
Any thoughts would be much appreciated.
Regards
Brian
