.61 Caliber is the same as 20 gauge.
Rifles are generally measured in caliber which is expressed as bore diameter.
A .44 magnum means a .44 inch bore; similarly countries with the metric system use metric bore measurements (ie. 9mm Luger)
Shotgun measurements are expressed in gauges. Gauge measurements are fractions of a 1 pound ball of lead. A one gauge shotgun shoots a one pound ball of lead. A 12 gauge takes 12 round lead balls to equal a pound and a 10 gauge equals a tenth of a pound. The smaller the gauge; the larger the bore.
The only shotgun I am aware of that is measured differently is the .410 shotgun which is approximately .45 caliber or a 67.62 gauge.

It would depend on the year, caliber and condition of the gun. You'll need to give out more information to get an accurate answer
the 12 guage is a caliber not a gun
a .45 caliber.
What caliber of man are you looking for? What caliber of gun are you looking for?
The short answer is no. The longer answer is, you might be able to get a .40 caliber cartridge to fire from a .45 caliber gun, but it may damage the gun, and even if it doesn't damage the gun, it will cause other problems. In general (with only a few exceptions) you should never try to fire any cartridge in any gun other than a gun designed for that caliber.
It is the standard .68 caliber
smaller the number, the smaller the caliber.
Caliber has nothing to do with it.
The word "caliber" refers to the diameter of the internal bore of a gun or firearm barrel.
Fifty caliber, but it is more of a toy than a paintball gun.
