[QUOTE="elkaholic, post: 678902, member: 13833"] Maybe I missed it but I didn't see anything concerning case prep? If you are not already doing these things, they will tighten up your spread. Sort your cases to no more than 2 grains variation. Make sure the necks are turned consistently to the same thickness and trim to exact length. ANNEAL THE CASE NECKS! This will help keep the tension more uniform case to case and thereby help equalize velocity. To prove the point, number 6 brass from 1-6 and then carefully load and chronograph each. Take the three most consistent and separate from the three most extreme and fire again checking the velocity. I am pretty sure you will find that the results (case to case) will remain consistent and the three that started out the closest will remain that way.......Rich [/QUOTE]
