[QUOTE="Bart B, post: 517076, member: 5302"] I don't think one shot per charge weight's enough to make a qualified decision on. The best commercial match ammo in a good rifle will hold 1/2 MOA at 600 yards with a 3/10ths grain spread in charge weight; with new unfired cases at that. The best proof your one shot per charge test's a valid one is to repeat it. Then do it again. If the results for all three tests are the same, then you're inside the ball park between loads 4 and 8. Finally, shoot one 20-shot group to get at least 80% probability that loads the best one. [/QUOTE]
