[QUOTE="8andbait, post: 1262536, member: 40850"] Basically same test as with the 6.5-06 AI except with the 7mm rem mag 66.4 grains of RL26 with 215 primer, 175 berger elite hunter bullet at .015 jump Frozen rounds went 2962, 2939, 2956 averaged 2957 with a SD of 11 Hot rounds went 2997, 3013, 2988 averaged 2999 with a SD of 12 47 fps Difference and a 2975 average for all 6. It was 1 degree this morning so the cold rounds from the deep freeze were probably 0 degrees and the rounds from the heater were probably 90 degrees or more, they were hot in my hand. So probably about 1/2 fps per degree or better. A 210 primer like I used in the 6.5-06 AI load may also get things closer. I am going to test Retumbo next since it's my go to powder in the 7mag [/QUOTE]
