air rifle idea.

[chinnerz]

here is an idea i had from looking at a few other pictures.

the system works via a hammer hitting a pin on the barrel its self, moving the barrel backwards, exposing a hole to pressurised air and pushing the projectile outwards.

will this work? and if it does, will it work well?

Something like this



A long time ago I had thought up a similar design powered by an electrically driven eccentric cam to give full auto:



Those were just concepts though, but Antonio had made a few working prototypes along those lines.

hmm, very nice. but with the whole barrel moving, will it affect the accuracy significantly?

That never bothered the Bofors series of autocannon or the Browning M2 50 cal

As long as it moves consistently it shouldn't be a problem.

To be honest, you're probably not going to get enough accuracy anyway that a well made moving barrel will notably affect things.

But, as Jack points out, the M2HB uses a moving barrel - what he doesn't note however, is that the M2HB was responsible for the 20th century's longest range combat kill, at ~2500 yards.

It's a record that has only been bettered twice, and even then only by a few percent - both times, it was done by a dedicated sniper rifle.

I didn't want to bringGunny Hathcock into the debate

Still a perfectly important illustration of what accuracy can be had out of a moving barrel - although it obviously can't add accuracy, it doesn't mean any has to be lost.

cool, well i will look into this idea, maybe draw up a few concepts of my own
