[QUOTE="Bart B, post: 561695, member: 5302"] 'Tain't necessarily so. Years ago, when several of us developed the load for Sierra's 155-gr. Palma bullet in the .308 Win. case, the load that the lab tested and produced the lowest spread in muzzle velocity and peak pressure was the least accurate of a couple dozen loads tested. The one we ended up using had a little less than average numbers for velocity and pressure, but it was the most accurate. Shot well under 4 inches at 600 yards in spite of 3/10ths grain powder charge weight spread. Lake City Arsenal's M852 match ammo with Sierra 168's had about 42 grains of IMR4895. They used a charge weight that produced best accuracy within pressure and velocity specs. And best accuracy didn't always have the lowest spreads in averages for these two things. [/QUOTE]
