Yes, the Medusa is one.
Ammunition shelf's were where the soldiers kept their ammunition and guns.
You can shoot them in a .357 Magnum revolver, but that's about it.
It depends on the gun. The question is a little to vague.
The Glock pistol in caliber .45 GAP.
You need to consult your owner's manual. Some BB guns can shoot pellets, but some cannot.
No. Different types of ammunition for different types of guns. There's no "one gun" that can fire all types of ammo.
It actually a type of ammunition. Instead of the firing pin smacking the center of the igniter cap, the rimfire ammunition is hit at the base. It is basically a wider percussion cap so you can not shoot high caliber bullets from them and they are only a one time use.
The Tokarev and Mauser "broomhandle" pistols were made in that caliber.
No. People just modify Nerf toy guns to look like real guns. They cannot shoot real ammunition.
I shoot the pests at my house w/ pellet guns, so no one know. But good guns for rodents/ gophers are 22 rifles, and small caliber guns. I advise pellet guns because they aren't loud but can kill rodents easily.
7.62 mm (or 30 caliber) and 5.56 mm (or 223 caliber) are common rifle cartridges. Pistols, machine guns, and artillery will of course be different from these.
First, Pellet guns don't shoot rubber balls, they just shoot pellets. But I know what you are asking. I believe you are asking about RAM (Real Action Markers) paintball guns. These guns shoot a .43 caliber paintball or Rubber ball, not the much larger .68 caliber paintball that is associated with Paintball games. RAM guns are used for training by the police and other agencies. They feel just like a real firearm and even have blowback when fired. Umarex co carries a line of RAM guns. See the link below.
