[QUOTE="codyadams, post: 1964885, member: 87243"] I have done that in my .260 AI, temp was 17° on the cold ones, and 67° on the warm ones (Wyoming summer morning, that was as warm as it got) and my temp variation was .15 fps/degree. Haven't tried them hot yet. One day I'll do a truely accurate test, rifle and ammo out in the cold winter air until all are ambient temp, then put em in the truck and wait until all are ambient temp of around 85, and chrono from that temp. About the only way I can see to 100% rule out all variables. Looks like those hammers are doing their job. I just finished up lpad developement in a 7 mag with the 143, took 16 rounds, including a max pressure work up/velocity test, and a 560 yard ladder test. Makes it nice. [/QUOTE]
