[QUOTE="Eric Musgrove, post: 2581553, member: 102783"] TODAYS UPDATE: I decided to take some advice and weigh some cases and selected some with-in a grain of each other. Also once fired, I started back at 58 of H1000 and went up to 59.4 in .2 gr increments. What ever the anomaly was disappeared. But it is interesting to look at the speeds side by side from both days, there is some thing odd that happened the other day but at this point I am going to move forward with the new data. Here is the link to the data, the forum jumbled it up and made it hard to read.

No heavy bolt lift, no ejector marks First 2 error then 2976, 2969, 2976 *No pressure signs While digesting data I decided to way the brass with the ejector marks and the others loaded the same and shot today. The cases were almost identical in weight with just a few 10th off. Range is covered and benches in shade, temps all 80-85F, even used same bench. Todays speeds are more realistic than the 15th.
