We do not discuss inline weapons.

Recent publication (Smith and Swick, 1997) of a small passage in a little known travel diary journal of a Thomas Rodney, who was a day visitor to Captain Meriwether Lewis while he was traveling down the Ohio River at Wheeling, Ohio in September of 1803, caused new thinking about the Lewis airgun. The passage reads:
“Visited Captain Lewess barge. He shewed us his air gun which fired 22 times at one charge. He shewed us the mode of charging her and then loaded with 12 balls which he intended to fire one at a time; but she by some means lost the whole charge of air at the first fire. He charged her again and then she fired twice. He then found the cause and in some measure prevented the airs escaping, and then she fired seven times; but when in perfect order she fires 22 times in a minute. All the balls are put at once into a short side barrel and are then droped into the chamber of the gun one at a time by moving a spring; and when the triger is pulled just so much air escapes out of the air bag which forms the britch of the gun as serves for one ball. It is a curious peice of workmanship not easily discribed and therefore I omit attempting it.”
Any airgun historian or student would immediately realize that this description could only apply to a Girandoni system repeating air rifle.
The Girandoni system was adopted, in great secrecy, as the Austrian military repeating air rifle (Hummelberger and Scharer, 1964/65). It has been recorded that the system was invented in 1780, but deliveries of these guns to the Austrian army did not begin until between 1787 and 1791. Hoff’s (1977) classic reference on antique airguns and Hummelberger and Scharer (1964/65) indicate that about 1500 Girandoni military airguns were produced and that finally they were retired from service to Olmütz in Bohemia in 1815.
[url] http://www.beemans.net/lewis assault rifle.htm[/url]Because of the sophisticated nature of the flat mainspring and the timed release mechanism, Baker and Currie (2002) suggest that the Girandoni system is capable of much greater power than air rifles of less advanced design (such as the Lukens air rifles). As of May 2003 they were only willing to indicate that this system could project a lead ball, of about one-half inch diameter, of about 210 grains to a muzzle velocity of at least 500 fps for about 117 ft. lbs. of muzzle energy. Colin Currie reported (personal communication May 18, 2003) that the Royal Armories of Leeds, England recently charged the Heiberger .433 caliber air rifle, a formerly single shot air rifle made about 1750 but converted to a 23 shot Girandoni-style repeating system[10], apparently in the early to mid-1800s, to about 800 lbs/sq. inch and achieved a muzzle velocity of over 900 fps with balls of 120.4 grains for a muzzle energy of 217 ft. lbs. He reported that 1500 strokes were needed to pump up the Heiberger”˜s buttstock reservoir to operating pressure after 20 shots had been fired from one charging/loading. ... The power levels discussed above were very potent for the period. However, foot pounds of energy do not tell the whole story. Few hunters today would venture after big game with the energy levels of the old big bore airguns or flintlocks, but those big lead balls, about a half-inch in diameter, have a special effect ”“ as does a deadly arrow with “only” fifty foot pounds of striking energy. One has to respect a gun capable of shattering a huge lead ball against a distant steel plate, especially when a typical Girandoni system gun could deliver about 20 of those heavy missiles within the minute and another 80 rather suddenly! (With practice, one can simultaneously load the gun with action of the left hand and cock it with the right hand - enabling aimed shots to be taken about every 1 1/2 seconds!). The simple great inertia and large diameter of those big lead balls also makes them far more dangerous than paper figures would suggest. Walter Hummelberger and Leo Scharer (1964) relate a great deal of the feedback from the Austrian military about the Girandoni repeating air rifles. While there was considerable complaint about their reliability, there does not seem to have been any complaint about their lethal effectiveness - they must have been of power similar to the flintlock Jaeger rifles of the period! And the fact that Larry Hannusch (personal communication, Nov. 27, 2002) indicates that he has now regularly used his Girandoni-system air rifle (a Lowentz, apparently with a less powerful mainspring) to take the huge whitetail deer of eastern America is simple and clear proof of the lethal power of these big bore airguns.

"Fully Automatic", as in, you hold the trigger in and it fires all five rounds in rapid succession?
Please do post a photo of this.
The modern incarnation of this system is called "Metalstorm" Google it sometime... :shocked2:Toomuch_36 said:Dale Brown said:Toomuch_36 said:There is also a five round, fully automatic flint lock rifle.

First I must appologise for the typo. my fingers hit the wrong keys, the date of the mentioned issues is 1987 not '67.
Dale I am afraid posting a photo is beyond my grasp at the moment, but maybe I can explain it well enough.
The base firearm used was a fusile and the origional touch hole was plugged and a new one drilled a ways up the barrel and the lock moved accordingly. the loading was five loads stacked on top of each other (powder, ball, powder, ball ect.) with the first four balls having a hole bored through them. When fired the forward most load was ignited and would flash back through each succedeing ball untill all rounds had been fired.
