[QUOTE="Pdvdh, post: 1394637, member: 4191"] I'm hoping some members can post any values they've settled on, tested over time, for their observed changes in muzzle velocity per degree F temperature change using RL26 powder. Convenient would be 0.__ fps change in muzzle velocity, per degree F change in temperature. I spent a good 45 minutes Google searching this Forum, as well as others. I find little consistency. Alliant claims to expect around 0.5fps/*F. Individuals post everything from -0.2 fps/*F up to more than 1 fps/*F. Yes that's a negative -0.2 fps/*F. The muzzle velocity increased in colder temperatures. Decreased in warmer temperature according to one post. A year and more has elapsed since many of these Posts/Threads. So anyone have some numbers that have been tried and confirmed over time? Hoping to receive some numbers that don't cover such a broad extreme, perhaps now that more members have additional experience with this powder. I'm just now trying RL26 with a 280 A.I. and a 30 caliber magnum rifle. Thanks. [/QUOTE]
