[QUOTE="memtb, post: 2064136, member: 75451"] I too have seen this “anomaly”(?), and described it a year or so back, in a previous post. Mine occurred with RL17. I always develop my loads on hot (90+) as to be certain that on a hot day, to make sure that my loads are safe in a high ambient temperature situation. We’ve always thought that pressures would increase when the rifle/cartridge were subjected to high ambient temperatures. My test was performed with ambient temperatures running between -3 to -4 F. The rifle and ammo were exposed to these temperatures for approximately 2 hours prior to shooting across the chronograph. While my increased velocity was minimal, it was completely opposite of what was expected! memtb [/QUOTE]
