[QUOTE="VD2005, post: 1076711, member: 89139"] So I'm hoping I'm not just crazy and someone could help answer this question or if their is a scientific answer. Recently I was shooting over a chronograph as I was working up some load data I had 4 different loads ready and 4shots each. this is in a 6.5-284 with H4831sc and fed215 primer As I worked up in powder grains going up .5gr each load I seen steady increase in velocity until I hit my last string. it was at 53gr. I believe this was around max I seen slight ejector markings on the brass. This load velocity drop by 46fps from my last one with .5gr less powder. Where I seen on average 70fps increase in velocity between the last 3 loads. Is their an answer for this? I have seen it befor in other cartridges but never could find a answer. [/QUOTE]
