It's not the speed of the pellet it's the size and the type of the pellet. Yes a .177 caliber pellet can kill a pig but it most likely would take several shots, depending on where you hit it. Also "Hunting or hollow point pellets" should be used. A head or heart shot is best.
I suggest At least a 25 caliber pellet should be used. If you can afford a a good hunting pellet rifle then I suggest a .25 cal Marauder, a 357 Rogue or a .50 cal Sam Yang. But these are expensive and have devistating power because they at PCP class rifles. (PreCharged Pneumatic) There are a few .25 cal springers or Nitro gas like the "Benjamin trail NP XL" that are a better choice than a .177 cal pellet rifle. .177 usually are not recommended for hunting anything larger than a rodent.
Yes, small game and rodents.
Rodents and small game.
You mean Air Rifle. Yes this is fine. Air rifles (Not AirSoft) usually fire between 500 FPS and 1200 FPS
1000+
Normally a 600-700 fps air rifle will kill a rabbit at around 30-40 yards away. So this will include a .22 caliber air rifle or if your looking for something with less power that will just kill birds, try looking for a .177 or .20 caliber air rifle but if you are looking to hunt game like rabbits go for .22
It's rated at 580 FPS.
any air rifle that fires a .177 pellet over 600 FPS should be sufficient
It's rated at 660 FPS
300 fps or 320
I doubt it.
This rifle is rated for 363 feet per second (FPS). That is slow in today's world where air rifles exceed 1000 FPS. If this rifle was in EXCELLENT condition and I do mean Excellent it would be worth $50. From 1969-75 Meyer & Grammelspacher of Germany made air rifles for Winchester.
I assume that you are asking about a PCP class rifle. It will kill just about anything you can hit. But I would stay away from Elephants and Bears. A head shot is preferred.
