[QUOTE="BUSTINDOGS, post: 2064071, member: 49798"] I have found the same thing. If the whole system is cold ( rifle and ammo) I get higher velocities. I would have to check my notes but with my 7mm SAUM using RL23 and FED215 from 68 degrees to I think it was in the teens this is where I would have to check my notes I had an increase in velocity. If the ammo is cold but the rifle is at 68 coming out of the house I would see a decrease in velocity. My control was the rifle and ammo both at 68. I can shoot in my back yard and living in MN I can test in some pretty cold temps -20 to -30 ambient and up into the high 90s on the other side of things. I have seen the same thing with other rifles and powders, too. [/QUOTE]
