[QUOTE="steve smith, post: 21444, member: 110"] Well hell! I just hate it when someone says here are a few things that may be the problem and I have to check off **** near every one. 1. Bullet olgive the same? Well there all from the same lot. I assumed that Matchkings would be fairly consistant. Using a stoney point comparator the seating depth varied by no more than .002 for most all the loads. But I'm still waiting for a set of Starret dial calipers so can't work on this one yet. 2.I use a digital (calibrated each time) for quick weight check but use a powder measure to get within a grain then trickel the rest into an RCBS 5-0-5 scale. I use calibration weights to check both scales every time I use either. 3. Nope! I've been sizing the full length of the neck. I use the Redding bushing neck die w/no expander. 4.Bullets are making it to the target. I checked for key holing and to make sure that one bullet made one nice little hole. They are making it to the target intact. 5.Nope! Not weighing bullets. I just weighed 10 and they seem to be right at 134.9-135gr. 6.Chrony brand. I know, but just trying to pay for the best equipment all at once is damned expensive. Plus I bought this one three years ago before I knew any better. An Oehler 35P is on my christmas list along with a strain gage. I'll just have to keep dreaming for a little while longer. [/QUOTE]
