It is called a tubular magazine.
the action
In a break barrel and pump rifle it located directly behind the barrel in a large tube. Rifles that use C02 usually hold the C02 bottle under the barrel.
A weapon that has one shotgun barrel and one rifle barrel either in an over/under or side by side configuration.
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.
If you have enough money, someone can make it.
I just bought 2 boxes of Federal bulk 550 - 22 long rifle bullets - 36 gr. for just under $15.00 a box at Walmart.
The forearm is the front part of the stock, under the barrel, that your NON-trigger hand holds.
I think 1 in 14, this is because it is intended for light bullets 50 gr and under. It would be cool if the twist was faster and you could shoot heavier bullets effectively but there would be way tooooooooooo much heat for that little barrel and it just wouldn't last!
Pull the triangle pin out from under the barrel and then slide the revolver out to remove bullets
It's on the table, under the big red sail roof on the upper level.
Requires hand on inspection.
There are two versions of the 317. The first version had a plunger right under the barrel, made between 1934-40. The second version had a pump handle under the barrel. It was made between 1940-69
When the triger is pulled, a pin in the barrel behind the cartridge is forced into the end of the cartridge igniting the powder charge. The ignition releases gasses under very high pressure which pushes the bullet out of the cartridge, down the barrel and to the target.
