The best way to find your effective hunting range is stump shooting, or shooting at 3-D targets, under the same conditions you'll be hunting in. So... if you'll be hunting from a tree stand, then it's shots from a tree stand that count. If you'll be spotting and stalking, then it's shots IN THE SAME KIND OF COUNTRY YOU'LL BE HUNTING, with the same range estimation techniques you'll be using, that count. I emphasized the same kind of country, because estimating range on flat ground, and shooting on flat ground, is a whole lot easier than doing either one in steep canyon country, for example. Furthermore, shooting on a flat range is a lot different than shooting from a cramped tree stand - and even more different than shooting on a steep hillside when you're exhausted from climbing around steep mountains or canyons all day. Also, it's only the first shot you take at a given target that tells you whether that target was in range.
Lots of good removable bow quivers - Great Northern, Selway, Thunderhorn, Kwikee, etc. 3 Rivers Archery has a good selection. Personally, I prefer a side quiver or a hip quiver for the kind of deer and elk hunting that I do. I use the Powderhorn Edition made by Art Vincent (Cedar Ridge Leatherworks), but wear it as a hip quiver rather than a side quiver. Art has a good website online.
