[QUOTE="Engineering101, post: 1165949, member: 63138"] jtmoose I don't know much about the subject but I have learned a couple of things which I'll mention. Larger calibers are inherently LESS accurate. Compare a 223 Rem to a 30-06. A good one of the former will beat a good one of the later. A longer barrel in a given chambering will give higher muzzle velocity because it gives more time for the powder to burn. A short barrel magnum therefore would not take advantage of the fact it is a magnum as more of the powder would travel out the end of the barrel unburnt. If you use a faster burning powder in a short barreled magnum to account for the short barrel, you have to reduce the amount of powder or end up overpressure which also defeats the purpose of the magnum. I suggest you get yourself a copy of QuickLoad and do some what ifs before you get too carried away. [/QUOTE]
