[QUOTE="rcoody, post: 1102573, member: 91090"] Sounds like you are headed down the right path. You assumed that your powder charges were inconsistent and ruled that out You assumed that the inexpensive lee dies were inducing too much runout and you eliminated that. now you are moving to seating depth. the OAL gage is a great tool. Knowing you chamber overall length is important. You probably already know this but each one of your bullets will have a different point where it contacts the lands. You will have a different measurement for each one. Now I am going to ask a silly question. How many different loads and what powder did you use in your original shooting for groups test. I recommend starting near the lowest recommended charge and with an '06 moving up in 0.5 grain increments until you get pressure signs or reach the max recommended load. When you did this did one powder charge stand out with the best group? [/QUOTE]
