Several different air rifles use the .177 caliber pellet. Each different model rifle can propel the pellet a different distance depending on the power plant that the rifle uses. .177 caliber pellets also come in different weights, this also has an effect on how far the pellet will travel. A PCP air rifles (PerCharged Pneumatic) that use a scuba tank to charge them to 3000 PSI can obviously out distance a C02 charged rifle in propelling a pellet. So you can expect a pellet to travel anywhere from a few hundred feet to over a 1/4 mile with ease. Depending on the rifle used.
A pellet weighing 7.9 grams can not exceed 826/FPS See the link below

Any air gun or rifle that uses a .177 Caliber pellet can use the Gamo .177 Red Fire Pellet. No matter who makes the air gun. The Caliber .177 is universal to all .177 caliber pellet guns or rifles.
It depends on the size of the hog, The size of the caliber, the weight of the pellet and if you can get in a good head shot. Assuming you are using a .177 caliber rifle. (your stretching the limits of the rifle) I would select a H&N Baracuda Match .177 Cal 10.65 grain pellet. Don't get hug up on speed. A heavy pellet will fly slower than a lightweight pellet but will fly straighter and have more knock down power than a lightweight pellet. Hopefully your going after really small hogs, because I think you are stretching the limits of you rifle if it's a .177 caliber air rifle. I recommend a larger caliber, but it's up to you.
