The "parent" cartridge was the .250 Savage, necked down to .22 caliber.
it might be for the Krag rifle, cal. 30/40..... not 30/06
The Benjamin 132 is an air pistol not a rifle, it uses .22 caliber pellets, not .177 caliber pellets. The 130 series of Benjamin pistols were models: 130 shot .175 Cal BB's 132 shot .22 Cal pellets 137 shot .177 Cal pellets If yours is a rifle then I have NO idea what it shoots
Yes
Not familiar with an atomic rifle. There have been artillery pieces that can fire an atomic shell, but not a rifle.
30 caliber
the maker.
no
A test
.22, 9mm, 45 ACP are among them.
Written as .16 caliber (notice the decimal point?), that would be a VERY tiny bullet- .16 inches in diameter. That is smaller than a metal BB- which is between .17 and .18 inches. Written as 16 caliber (no decimal point) it would refer to the length of a cannon barrel- 16 times longer than it is wide. But you may have caliber confused with gauge- shotgun shell sizes are usually given in gauges. A 16 GAUGE shotgun is about .69 caliber- or .69 inches across the shell. They are smaller than a 12 gauge, bigger than a 20 gauge (with gauge, smaller number means bigger)
Less than .01 cents
Caliber refers to the diameter of the bullet the gun is designed to fire. When referring to cannon, caliber may be used to indicate the barrel length. A 5 inch 38 caliber Naval gun fires a 5 inch diameter shell from a barrel that is 38 calibers long- or 38 times 5 inches (190 inches, or 15.83 feet) Please note that with a handgun or rifle, caliber referring to bore diameter is a fraction- such as .308, .45, etc. With cannon, it is a whole number, and given along with the bore diameter in inches.
