[QUOTE="rcoody, post: 1109273, member: 91090"] Eliminate the variables one at a time to find the cause. A lot of people want to ignore flyers but they are representative of what the real group is. Try a 20 shot group and see if the flyers are an anomaly or are really representative of the actual group. You should be able to find a powder charge that has consistent POI for at least 0.3 gr. Find that accurate load and then check above and below in 0.1gr increments. You would be surprised what a tenth of a grain can do to a group neck tension is very important. I recommend only neck sizing. I use the lee collet neck sizer because I don't like donuts. I neck size rotate the case and neck size again. Have really good luck with runout I only use CCI benchrest primers, I weigh my powder charges to 0.02 gr., when I am seating bullets if one doesn't feel quite right it goes in the cull pile, after loading I check all finished rounds for runout. If it is more than 0.002 then it goes in the cull pile. [/QUOTE]
