[QUOTE="rscott5028, post: 491083, member: 24624"] Kevin, Is it also true that: (a) atmospheric temp as accounted for in most ballistics software does not account for the powder sensitivity (i.e. delta MV) Rather, it's about temp/pressure/drag in flight (b) the temp sensitivity you described pertains to the temp of the powder in the cartridge at time of ignition (c) temperature of the barrel is mostly irrelevant unless the cartridge sits in the chamber long enough to absorb the heat ?? thanks, richard [/QUOTE]
