[QUOTE="Pdvdh, post: 1324728, member: 4191"] [B]Re: The .338 Rogue _ RL33 MV vs. Temperature Data[/B] I've recorded additional bullet velocities from my .338 Rogue with the 300gr Berger OTMs. The additional velocity recordings have allowed me to refine/improve my MV versus Temperature relationship with RL33 powder. Here's the data I'm currently using in my ballistics program, and I now place pretty high confidence in this data, between -4*F and 68*F. 68*F is about as warm as it gets here. Therefore I have no recorded bullet velocities in temperatures above 70*F. [ATTACH type="full" alt="RL33 MV Versus Temperature _ 7-5-2017.JPG"]83301[/ATTACH] I am pleasantly surprised. I hunt in temperatures between 41*F and 68*F. In those temperatures MV increases at an average rate of 0.5fps / *F. Not bad at all. My MV dropped off at a much greater rate as temperatures fell below 23*F, so for winter hunting the powder would be more temperature sensitive in my .338 Rogue. I'm getting to old to hunt in the COLD anyhow, so no big deal for me. [/QUOTE]
