BIG BORE 909S by Sam Yang: I just ran across this rifle while surfing the web with a friend. We were having a friendly debate over how fast a paint ball gun or air gun could conceptually propel a pellet far heavier than a .177 or .22 pellet. His adult son claimed that Lewis and Clark carried a large caliber air rifle for hunting on their expedition, which is apparently true. We were both astonished to find these types of modern air rifles, as neither of us had ever heard of them. This is a .45 caliber air rifle capable of propelling a .45 pellet up to 750 fps. Hollow point and round nose .45 pellets are available in weights from 180 grains to 225 grains and higher, and one author claims any 0.451-cal. to 0.452-cal. lead bullets can be used. It seems to me that this is approaching the power of a .45acp? Would it be possible to hunt white tail deer with such a rifle as this? Can anyone tell me the whether a 200grain bullet travelling at 750fps is adequate for deer? What is most intriguing is that these rifles can be recharged using a three stage hand pump (though a scuba tank is highly recommended for extended shooting.) This rifle, if it can conceivably take moderate game, seems to be a perfect gun for living "off the grid."
