[QUOTE="live2huntmt, post: 1303661, member: 75903"] Ambient temperature is within 5 degrees. I have documented the change in velocity and temperatures in the first 100 rounds and have plenty of data to compare these loads to...I can guarantee you it is not a temp sensitivity issue. Max pressure on this load is producing around 3175 fps(ejector mark and barely stiff bolt). I am trying to achieve 3025 fps (150 fps below max). Using virgin brass I could do this using 96 grains of RL-33...using resized brass I now have to use 92 grains. I measure my bullet seating off of the ogive using a Hornady bullet comparator. New virgin Nosler necks measure .337", loaded they are .339" and fired they are .341" I am using the same lot of Berger 230's. [/QUOTE]
