Interesting! I have a Du-10 which has exhibited all of these problems (except automatic fire) at one time or another. Pellet selection seems to be critical, but with everything checked and serviced, the best I can get reliably is four pellets delivered correctly. Load 5 and it becomes unpredicatable. An added safety issue is that some pellets will jam, making it possible to assume there has been a multiple shot when there has been a missfire. I've taken to opening the breach and sliding a cleaning rod up the barrel in these instances 'just in case', it would otherwise be all too easy to put the pistol away with a pellet in the barrel. It's accurate, it's fun, but it's not without problems.

As best as I can make out, the system works on the basis that a claw in the barrel catches the skirt of the front pellet and holds it in place. Gas is introduced behind the head of the pellet and nudges it past the claw on firing so that the pellet is then ahead of the gas inlet. As the pellet travels down the barrel the back pressure re cocks the pistol and the spring in the bolt pushes the second pellet forward. If the second pellet isn't caught by the claw there will be a multiple shot with two or more pellets discharged at the same time (usually leaving just one hole in the target). If a pellet is held too frirmly by the claw, it jams. The 'automatic fire' problem is different and (I think) trigger related.

The system is clever. The engineering isn't. Are there any better pistols with this system?

Not the same loading system, but the Aeron BRNO B96, Steyr LP5,Steyr LP50 spring to mind for 5 Shot pistols. The price tag does reflect the quality.

True, but I don't think there are any other pistols that use the DU10 system, and probably for very good reasons.

I've tweaed my previous post to remove any confusion.

All the pistols I mentioned use a sideways moving "box" magazine, and this does seem the best method for consistency.

Most clubs always raise an eyebrow when somebody arrives with a DU10, and my last one bannd them outright. Not only for the potential of full auto, but also because they dump the remaining gas when the pressure drops, which can be off putting to the next shooter. This had also been mistaken for full auto by the uninitiated.

Kind regards,

Don't know what your club would make of a Crosman 600 then!
Also many co2 pistols vent gas when finishing.
I am tempted to call that Clubs members girls but am not allowed to these days.

You had to be there!

Our latest club allows any legal airgun, as long as it is handled and shot safely.

I have never seen the point in having rules that greatly limit the guns that can be used.

Kind regards,

Our club has two rules.
1. Don't shoot anyone
2. I am the Boss
As I am the Boss it is difficult to pass new rules.
