I live in Fl so the temp swings are not nearly as great.
Thanks for the info. From what I understand, it's the higher tempratures that cause the most problems with velocities, not the low ones. And being from FL I'm sure you have shot in plenty of warm temps, so Im sure you would have you would have experienced some velocity spikes if it was sensative to the heat.
Since my first post I ran across another post here that had a link to a balistics lab report from some people at Barnes bullets . They had done a little testing of several different powders and primers for velocities at different temprature extremes. Ramshot magnum and H1000 were a couple of the powders they tried in the magnum caliber. It showed that the Ramshot was comprable to H1000 and they were the best two they tested. The other two tested with the 300WM were IMR4831 and RL22, both showing signicant velocity spikes with the high temps.
Not sure how extensive their testing was, and it was with only 4 powders with the 300WM only. But it does appear that the Ramshot should be , as you also said, quite stable.
