I find that interesting, regarding the temperature changing velocity. We know that every 15 degrees change in temperature changed you bullet impact 1 MOA.

I did some testing a while back regarding High Power rifle shooting. After the barrel/chamber got hot, the difference in velocity of the round if, for say you chambered the round while waiting for target repair (scoring and pasting) and loading the round after the target comes up and the instant before you shoot.

I don't know what I did with my notes, but I do remember there was a difference in velocity.

Thanks for posting that link, it kind of explains what I did.
