[QUOTE="brentc, post: 1370874, member: 16938"] I figured I ought to throw this 300 WSM testing in here for guys looking for more data. I took 10 rounds to the range to get velocity data from 68.7 grains of RL26 with the 200 ELD-X seated at .020" off. The temp outside was 17*F. For the test, I let five rounds of ammo soak in the cold for 25 minutes while traveling to the range and an additional 30 minutes to let the rifle soak alongside the first five rounds prior to firing them across the Magneto speed. The first 5 rounds soaked nearly an hour and the rifle soaked for 30 minutes at 17*F. The other five rounds were stored indoors at 70*F until they were fired through the rifle. My 17* F speeds were: 1. 3009 2. 3010 3. 3007 4. 3013 5. 3011 AVG 3010 fps For the warm rounds, I moved the rifle indoors to soak for 30 minutes at 70*F prior to firing the warm rounds. The warm speeds were: 1. 3017 2. 3019 3. 3013 4. 3020 5. 3015 AVG 3017 fps Needless to say, I'm pleased with what I'm seeing with RL26. A 7 fps swing over a 53* temp change producing 3000+ fps with a 200 grain bullet in the WSM case with RL26 exceeded all expectations. I'll test it in the negative temps in the near future for additional data. **Update** I've increased the powder charge to 69.3 grains to match the above velocity with a fresh 8lb jug of powder from a different lot. I see no indications of excess pressure and no change in accuracy. [/QUOTE]
