[QUOTE="bounty hunter 2, post: 1111017, member: 90711"] I too felt that 3500 fps with such a light weight 243 cal bullet was relatively unimpressive. However I also understand that most often supreme accuracy comes at a less than impressive velocity. In these small calibers if you don't have accuracy you don't have anything. With the quoted load of the light 243 cal bullet at 3500 fps using a prairie dog max point blank range or say a 6" top to bottom target your dead on hold is going to be something near 350 yards give or take. Not too unimpressive when compared to other cartridges used for PD shooting. Some of the rim fire cartridges come to mind there. Another point in favor of using loads that are substantially less than max potential for the cartridge is barrel life. One of the factors involved with barrel ware is pressure. Loading to a reduced pressure will extend barrel life all else being equal. An example might be that say you shooting a .224" 70gn bullet in a 223 Rem as well as a 22/250 Rem both at 3000 fps. Even though the bigger case 22/250 at normal pressure will normally erode a barrel faster than the smaller case 223 in this case maybe not so. Why? Because of the reduced pressure loading in the bigger case in the example. This is why the traditional chambering's for African hunting used such large cases. Not to reduce barrel ware but to deliver the same ballistics as smaller cases of like caliber at much reduced pressure. So in short having a large case for caliber but using it at less than its full potential has merit in that it can equal the ballistics of a smaller case in the same caliber but do it at lower pressure and extended barrel life. But then its always interesting to forgo the benefit of reduced pressure loading and put the hammer down! [/QUOTE]
