[QUOTE="KYpatriot, post: 1023688, member: 48028"] Also make very sure when using this method of load development that you are shooting a level rifle. You are trying to discern a very small vertical component of group size and any cant in your elevation adjustment will muddy it up. Also, you may want to blow up the size of these groups so you can " zoom in " on the vertical caused by velocity variation by shooting a farther distance. The 7rm and berger 180 hybrid is a very high performance LR round combo that minimizes these errors so you may need to get out 800 to 1000 to discern these velocity errors more easily. The caveat Of course is at those ranges it is even more important to pick a good day to minimize environmental influences like wind or mirage. [/QUOTE]
