anyone know anything about these knew sheridan air source rifles? they look ok, (as long as they provide a cover to conceal that ****** cannister) but i havent heard anything about them... is co2 still considered to be generally less accurate? ive just exhanged my gas ram for a couple of pistols as i have nowhere to use the rifle at uni, but will be looking to buy another rifle come summer when i am at home again, i dont fancy pre-charged and was wonderin if these airsource things are a viable alternative- 200 shots from one cannister isnt so bad but i seem to remember there being a general opinion that co2 wasnt accurate enough for hunting... any thoughts?
