The Giradoni repeating rifle. Designed in 1779, in the age of muzzle loaded muskets. It was a magazine fed pre charged pneumatic military air gun with a 20 round magazine.
Each cylinder (screwed into the back of the gun), was good for 30 shots.
Even cartridge rifles with magazines were only good for 5-10 shots by the turn of the 20th century.
For its day, it was a superb bit of technology. |

Disappointing he didn't fire it. Is fire the right word for an airgun? Shoot is probably more accurate.
Amazing technology for it's time though.
1,500 pumps is a bit of a downside but 3 air tanks giving 90 shots is far more than a musket could fire before it needed a proper clean. I doubt many musket men fired that many shots in a battle.
I like that site, I've watched a few of their videos.

I imagine the air tanks are very fragile now, might not be safe to fill them.

Well my BSA Ultra SE gets pumped to 232 BAR and is good for 40 shots at 10.5 lbs of force per shot.
I've no idea how much pressure goes into those tanks, but for 30 shots at equivalent power to a firearm, it's got to be a lot more pressure which would explain 1,500 pumps.
Additionally, the pump would introduce moisture. The last thing you want in an air cylinder.

It would rip you to pieces.

It would rip you to pieces. Just read your air rifle thread over in the other place. Some interesting stuff. I have a fairly cheap 177 break barrel with telescopic sights but I rarely use it. My right eye has always been weak due to being astigmatic but the scope helps a little with that. Without a scope I have to shot left handed as I just can't see the target well enough. I had corrective glasses as a kid but they really didn't help much so I stopped wearing them and I just wear reading glasses now. |

.177s are the most economical and with good pellets offer consistency of grouping too.
The Pre Charged Pneumatic I bought, I got the breech loaded single shot one because it's better for target shooting.
That's scoped but as the pressure drops the grouping widens as there's no regulator (yet).
I will get it modded one day, but it's a complex job and beyond my skills.

The last time I used it was to dispatch a mouse that was stuck to a sticky pad.

I'm mostly into target shooting.
When I drive a long way to shoot firearms it costs a fortune for a small number of shots. Air gunning gives me hundreds of shots for under £4. That's less than 5 rounds of .303.
And recoil from an air gun doesn't give my shoulder a whack.
