[QUOTE="ken snyder, post: 599256, member: 26019"] The longer the range you shoot the more important consistent velocities become. The larger the diameter the bullet the easier it is to achieve consistent velocities. An example would be that with a .375 its pretty hard not to shoot duplicate velocities all day long. with a small cartridge everything becomes more critical. For 6.5 - .30, most should be duplicate. I do not give any consideration to the standard deviation but weight it entirely on the maximum spread from slowest to fastest. About 11 - 14 f.p.s. spread without any odd balls is good enough. I do how ever hit the std deviation button once in a while and it generally comes up 5 to 7 on short string sampling [/QUOTE]
