[QUOTE="britz, post: 170397, member: 7865"] You may want to punch out the balistics on a calculator to see if you can keep it supersonic. Shooting a Sierra 77 gr you need to break 3000 fps to keep it supersonic at 1000. But the Sierra 80 grain you can easily keep above mach one to 1000 at 2780 fps muzzel. Not much advantage to go to the 90 grain balistically speaking in a 223 because you just cant push it fast enough to make much difference. [/QUOTE]
