TRIVA FUN

Good one James, I had to look it up. After I saw it, recalled seeing a box of ammo for sale at a gun show. Now I know!!



Can anyone name this or what it was designed to do?

I don't think the image resolution allows you to see the name...at least I can't on the iPad.

It actually fired a rocket propelled projectile. I recall seeing one for sale, but have never fired one or seen one fired, only on TV many years ago. Haven't seen one since. Don't recall what the name was.

That is the infamous Gyrojet. It fires as self contained rocket projectile. There were some as you might imagine downsides to the design. There were no fins on the rocket for stabilization but the exhaust ports on the projectile were set at an angle to spin it somewhat. Still accuracy was rather poor. Another downside was the projectile was ineffective if fired too close to the target as the rocket would not have achieved its maximum velocity yet. It would just hit the target and sit there and spin out its fuel. One upside, is that it would sort of almost work when fired under water. There was also a carbine frame you could put the pistol into to gain a longer sight radius. The whole concept worked better on paper than in fact.

Many years ago Shooters Bible had an article on them. Think it was in the mid 60's.

The military now has something similar Stacked jet cartridges & it is claimed to be able to shoot a million rounds a minuet.

What was the Duck Foot???

What was the Trap Door??/

Long after repeating arms were sold, the army continued to use single shot rifles. Why??

Trap Door was the moniker given to the Springfield Carbine. The breech flipped up and forward (like a trap door) to give access to the chamber.

Just a guess, but I would say logistics and procurement. The armories could only make them so fast, and then they had to be delivered to the troops.
Also, some of the "top brass" thought that soldiers wouldn't be as accurate if they had multiple rounds of ammo at their disposal.

Pretty much correct.
Army did not want them wasting or using ammo to fast.

During WW2, did Japan ever attack mainland USA??
How & did it Work???

Japan sent balloons with bombs over western USA. A woman was killed by one in the State of Oregon. HS

I believe Custer's troops were armed with the Springfield, in a 45/70 caliber. We all know how well he made out. I have read that upon repeated firing, something in the mechanism of the old Trap-door Springfields expanded to the point where the empty cartridge was almost impossible to eject. This didn't help much either.

I don't recall the specific details, but a Jap sub lobbed a few shells into mainland soil. Once in California and another time in Washington...I believe. Think the crept up a river or inlet a ways to do so.

Duck foot was a nasty looking multibarrel pistol that the barrels fanned out from a central location. All barrel's fired at once. I can't imagine it being that effective, but I guess with several barrels pointed at different angles it would be hard to dodge the fusillade of lead. :laughing:

The rest of the questions have pretty well been answered. Speaking of Japanese subs, did you realize they had one in WWII that was an underwater aircraft carrier? yep it is true. I believe it only carried 3 aircraft, but still a rather neat concept, especially for the time
