you can use a baloon, or a condom, as soon as you pull the trigger the explosive gasses will push the cover off before the bullet leaves the gun. FOOL PROOF!
That would depend on the caliber, and type of bullet, the rifle uses.
The Crow magnum (Eliminator) is a break barrel air rifle manufactured by Theoben (UK). It is a serious hunting rifle.
Yes there are many fine double rifles out there, they do tend to be pricey.
rifle barrels may have a different external diameter. A rifle that is carried for hunting will usually have a "sporter" barrel- slender, to save weight. Target rifles will have more massive, stiffer barrels for accuracy. Those are "heavy" barreled rifles.
Well, yes and no. Support should go under the forearm, not the barrel. When a support is placed under the barrel, it MAY change the point of impact. The pressure of the forearm on the barrel may change, and the normal vibration of the barrel is changed. For a hunting grade .22 rifle used to 30 yards, you probbably would not see a difference. For a long range target rifle used at 500 yards, you WILL see a difference.
I do not personally, but yes, there is a single shot rifle that can have the rifle barrel replaced with a shotgun barrel.

A gun is a firearm whose barrel is not grooved (rifled), as with a shotgun, for instance. (A firearm whose barrel IS grooved is called a rifle. Examples include the common hunting rifle as well as the huge rifles on navy ships that can lob a shell as far as 25 miles. A firearm is composed of a barrel, a triggering mechanism, a chamber, and an explosive cartridge and bullet.
No.
One difference is that the inside of a shotgun barrel is smooth and the inside of a rifle barrel is what they call "fluted" which puts rotation on the bullet as it moves though the barrel.
