I just inherited a gun and I need to learn about it. Pic is of gun. Is the ammo readily available? Remote is a size comparison.
Well, you've got yourself a little Saturday night special. That particular one was made by Sundance industries and is pretty much identical to the raven / Jennings made ones.
Those guns are known for being very inexpensive and they are the weapon of choice for gangbangers and criminals who want something that is cheap and disposable.
They are rough guns and not particularly well made, reliable, or pleasant to use but most of the time they will put bullets in the general direction of what you would like to ventilate.
.25 auto ammo is available but it is a very anemic caliber, comparable to .22lr but centerfire rather than rimfire.
Centerfire has the primer in the center of the cartridge, more reliable, simpler to reload.
Rimfire is for smaller rounds like .25 and .22 where the pin strikes the rim of the cartridge and it's more likely to misfire and more difficult to reload.
