[QUOTE="groper, post: 466778, member: 12550"] The problem lies within the standard twist rate barrels in 30cal. Its not the projectile makes fault... The standard 1:10twist barrel would not be able to fully stabilize a 230gr VLD shape bullet. It would have to be very long in order to have a secant, large radius nose and 230grains in weight. And whilst your asking for something in .308win, how fast do you think you can safely push a 210gr bullet, let alone a 230gr??? The 308win is already flat out pushing a 210gr @ 2600fps if your lucky... There is nothing more to be gained by going to a heavier bullet because what you gain in BC, you will loose in velocity and time of flight. This is no longer true for the big 30`s, as they have plenty of velocity already, they are simply lacking a bullet with a higher BC. Its the BIG 30cal cases that would benefit from a heavier VLD... but again, its only possible if people suddenly start buying faster twist barrels to shoot them... but why would you buy a faster twist barrel when you dont have the bullets available...? chicken or the egg, catch 22, conundrum...
