Well, it would help if you would tell us a little more. Or anything more. Bolt action shotguns are usually inexpensive. Bolt action rifles are often inexpensive, or even cheap, but some are very expensive.
To give my own example, I purchased a military surplus Mosin Nagant bolt action rifle in April, 2010 for $89.95. I purchased it online from J&G Sales. I also had to pay a $50.00 transfer fee to have it shipped to a local gun shop. The fee is actually paid to the gun shop. Still a good deal for the price, and the quality of the firearm was very good. I regularly shoot the rifle at an indoor range at paper targets. I enjoy target shooting, and it's relaxing. The ammo costs me $8.95 for a box of 20 rounds.
how much are they
How much what? Weight, value, use?
The Garand rifle is a semiauto, not a bolt action. Do you have a Model 1903A3 bolt action? A Model 1917 bolt action?
A utility bolt action 12 gauge will bring from $50 to $125, depending on condition, at most auctions.
A model 1904 is a single shot bolt action rifle.
Considering the size of most pellets, there is not much of a reason for a large Bolt Action air weapon. But yes there are several bolt action pellets guns and rifles. An example is the Crosman 2240. There are several "High Powered" air rifles, PCP's, (PreCharged Pneumatic) that also use a blot action, The Benjamin Rogue 357 the Marauder and Marauder pistol all use a bolt action system. I own at least 5 or 6 bolt action air guns.
