Sweetness, air rifle question
First welcome to the air rifle/pistol community.
Both are good to have around and both have specific task.Pistols and rifles are good for small game, and some bigger game if you know where to shoot. My brother has a rifle and he takes down small game ( squirrel and rabbit ext ) from anywhere between 10 yards to 70 yards with no problems. I have a pistol and I regularly clean out my barn of rats with it, and thats from point blank to a max of 5 yards indoors ( but it can kill mice up to 10 yards ).
As I said before both guns have their place, so dont go thinking one can do the others job...they cant. I'm not talking about the elcheapo walmart guns anymore, treat these guns properly or someone will get hurt bad. You asked about pistols, short answer: yes, they work great for indoors and when using the right ammo, they have do little bouncing/causing external damage. You can get either spring powered or Co2 powered pistols. I prefer the Co2 because you get multiple shots rather than having single shot before reload. Both these types can offer very high speeds, so take down power is your option, you can go as low as 200 up to 800+ fps.
And onto air rifles
Today's air rifles are ( in my book ) right up there with firearms. 100 yard shots are now capable with some of the top end guns, and in pellet gun terms, thats like 1,000 yards.
There are a few different types of air rifle, pump, break barrel, and PCP. Pump rifles are your basic, cheaper line of air guns. As they are called pumps, you pump them once or more to store up air to fire. Break barrel rifles are just that, you "break" the barrel which compresses a spring or a piston ( NP of nitro piston ). And a PCP stands for per-charged-pneumatics, which is basically what our paintball markers are, there is a pre charged tank that you attach to your rifle and you use an external air source to fire the pellets.
Pumps are plinkers and are generally used for target practice. I HIGHLY recommend that you do NOT kill with these rifles as they generally do not get the round moving fast enough to kill. My personal opinion is a minimum of 500 fps at a max range of 20 yards and closer. Anything less in speed or further in target range you risk not having a clean kill.
Break barrels are most common among hunting rifles. You can get either spring or NP. I personally recommend NP because you cant wear it out like a spring, your speeds are way more consistent, and you get upwards of 50% more power from a NP...and cold dose not affect it because its filled with nitrogen
PCP's are the top of the line in air guns. They can match ballistic specs of a .22 rifle and still be legal in gun banned states. A PCP uses an external air source ( typically an air tank ), and is most commonly bolt action/single shot fired.
I can drone on and on if you want me to, but just check out these guys and see what you like. http://www.pyramydair.com/
