[QUOTE="Pdvdh, post: 1556085, member: 4191"] Some folks test powder temp sensitivity by only cooling down their ammo, with their rifles remaining at higher temperature. They also report lower MV with solely cold ammo, by and large. Also, the bullets would be a little smaller in diameter at the colder temps also. Not just the barrel. Just some thoughts to ponder... When I test, both ammo and rifle are brought to the same ambient temperature. Which means I don't let the barrel get hot during testing. One shot, and the gun is left alone until it comes back down to temp. Which is just one more reason why my testing is so time consuming. [/QUOTE]
