RL25 is a good powder for velocity and accuracy but not very good for temp sensitivity. Retumbo is much better in that respect and gives at least as good velocity and accuracy. (at least in the 3 RUM's I've had).........Rich
ok thanks for info. It seems like everybody is getting best results with 97 grains of retumbo. That's a compressed load. Never loaded a compressed load. Is that tricky.

I have experienced this also, same powder. 300 fps delta from winter to summer.
Retumbo is my powder of choice for a hunting rifle in 300RUM
