one has to do a LOT of shooting for reloading to PAY for itself, then for one to SAVE on ammunition, one must shoot even more. if one is just a hunter, one who kills a couple deer per year, maybe an elk every 3 years, hunts ducks 5-6 times a year, hunts squirrels 7-8 times a year, and zero's his "deer " rifle once before season opens, it will take many years to see a profit by reloading.
think about it. the average big game hunter (and repeated surveys have shown that the single most popular game animal in america is the whitetail deer) gets to hunt 4 weekends per year, that's only 8 days! how many times do you need to shoot your rifle before you are ready for your 8 total days of hunting? and how many times are you going to shoot at deer? for the average guy, just one box of factory ammo will last a couple years, if not longer.
however, if one enjoys just shooting (targets, cans, yotes, prairie dogs, etc.,) and gets to the range on a very regular basis numerous times a year, and has a keen interest in accuracy - then reloading is the ONLY way to go.
