[QUOTE="elktaker, post: 1996269, member: 86786"] 2800 fps is only going to do what I want with a 156 gr bullet with a .679 BC. A 308 is not going to be able to keep up down range. Example of some: 6.5 PRC at 2800 fps with the 156 800 yd drop 19.3 moa 10 mph wind 4.4 moa and energy 1143 ft/lb 308 win at 2800 fps with 155.5 Berger's 800 yd drop 23.0 10 mph wind 7 moa and energy 748 ft/lb Seeing the 2831 fps is the fastest max load for a 308 win with a 24" barrel and the 155.5 in my Berger book, a short barrel would not match likely that. If we use 1000 ft/lbs as needed energy for a deer the the 308 win is done at 600 yards with a 24" barrel while the 6.5 PRC will get me to past 800 with a lot less drop and even more important less wind. To match the ballistics of at 800 yards of a 156 gr 6.5 Berger at 2800 ft, I would have to push the 308 155.5 great bullet to 3200 fps. I could go heavier with a 308 and up that a little bit but going to a 19" barrel the 308 will never catch the 6.5 PRC at 800 yards. I think 19" is going to give me enough of a buffer to find an accurate load over 2800 fps with the 156s. [/QUOTE]
