Well , I will admit to eyeballing several really low priced .264 s I've seen on the used racks lately . I figure a 120 to 129 6.5 bullet at 3300 to 3400 will give you both the speed and high b.c. One might make a genuine 400 yard point blank rifle , or at least come about as close as anything can ............ a 95 gr V-max at around 3700 wouldn't look too bad for a far out song dog either .......
