[QUOTE="el matador, post: 1298779, member: 12193"] Just a note about bullet drop: Every bullet ever made drops at the same rate, which is determined by gravity. Based on the time of flight you can determine how much a particular bullet will drop at a given range. To cut bullet drop in half you'll have to increase average velocity by around 40%. These 6.5mm bullets going 3750 fps are not going to shoot "flat" out to 800 yards unless you zero at 800 yards, but they will arrive at the target quickly and reduce bullet drop somewhat. The accuracy of a rifle has very little to do with what cartridge you're shooting. A 6.5 caliber isn't inherently more accurate than a .257, although your individual rifle might be. All of that being said, I think the 6.5-300 would be an awesome round. Brass and dies are easy to get, which is something you can't say for the Allen Mag. Also, if you research the 7mm RUM a little bit you'll find its pretty inefficient in standard length barrels. The 28 Nosler gives you about the same velocity while using 10 grains less powder. In a longer barrel you will notice the difference. You won't get advertised velocity out of the Allen Mag unless you use a barrel that's 30"+. If I wanted a fast 6.5mm for hunting I'd build a 26-28" barreled 26 Nosler, 6.5-300 Win Mag, or 6.5-300 Weatherby. I'd shoot 140+ grain bullets well over 3000 fps and be one happy camper. [/QUOTE]
