[QUOTE="RockZ, post: 391571, member: 5750"] Group #3 could be what Dan calls a "scatter group" Usually the OCWis about 1-2% above that load, which would be in the 46-46.5 range. Looks like things are coming together at 46.4gr. so I would work around that charge. I would try another round robin starting at 46.2,46.4,46,6,46.8 if the upper charges are within safe pressure ranges. If you think you caused it, then load that charge of 45.6 up again and shoot it to make sure. If it groups tight and in the same relative position it could very well be your OCW I think it is most likely the chrono problem since you are carefully weighing the charges. [/QUOTE]
