Awright, I'll post the answers. Just please don't beat me no mo!
1. The 45-70 was designated by caliber (45) and the charge of black powder in grains (70) OTHER rounds may use length of case, or year of introduction.
2. .357 Magnum was first brought out in 1935. Unveiled in late 34, but on the market in 35. ONE of George Patton's ivory gripped revolvers was a .357 Magnum.
3. The Pedersen Device was a WW I invention that replaced the bolt on the 03 Springfield 30-06 rifle, and permitted SEMI AUTO fire of a small .30 cal pistol type cartridge from the rifle. EXTREMELY scarce to find one- they are worth a new F-150 pickup!
4. The M-3 carbine was a modified M-2 (full auto) with an infrared night scope, and a BIG battery pack. While you don't think of a .30 carbine as being a sniper rifle, when you can see in the dark, and the other guy can't- it is a sniper rifle. Used in the Pacific campaign in late WW II.
5. The letter R at the end of a cartridge designation indicates a RIMMED case, like 30-30, or the cartridge for the Moisin-Nagant rifle. 30-06, .308 etc are rimless.
6. Taking it's name from the small boat that mounted it, a Punt Gun was 2-6 gauge, fired a pound or so of shot, was used by market hunters to shoot an entire flock of ducks with one shot (and sometimes, sink small boats from recoil)
7. Yes, Virginia, there WAS a real rocket pistol- the MBA Gyrojet. Lack of accuracy and extreme ammo cost were it's downfall.
8. One of the earliest self contained cartridges was the pinfire- each round had it's own firing pin- the gun had none. Expensive to make, awkward to load, and falling down wearing a bandoleer of pinfire shotshells would make you really popular with your hunting companions.
9. SAAMI (Sporting Arms and Ammunition Manufacturer's Institution) actually lists very few OFFICIAL +P loads- However, ALL .38 Super ammo is considered "+P"- since it is identical in dimensions to the earlier (weaker) .38 Auto.
10. While I love my .45, it was not the biggest. Before the cartridge revolver was the Remington Rolling Block pistol, an Army and a Navy version, in caliber .50 Remington. Dates from about 1870, not popular, due to slow rate of fire- but would make a DANDY club!
Thank all of you that tried your hand- if you like, will put together another quiz for next week- Now let me see- what WAS the bullet weight for the .307 Schneelock Triangular Revolver cartridge......
