.300 Win

We used it in Namibia...20 deg at daylight, 120 deg by noon! If there was any diff in zero or bolt lift, we never noticed it!

I use RL22 all the time and in a variety of rifles. Of course there is temperature sensitivity. I have not, however, observed serious degradation of velocity when shooting in colder weather. I do check my POI at each season so that I know my load.

I'd go with the 180 gr. Partition and be completely satisfied. A Partition is never a mistake!

Got 4 boxes of 168 TTSX to throw into the mix...lol
Seems RL22 is the powder. Has anyone experienced temp sensitivity with it?

IMO, 180gr bullet is the most ideal weight for the 300WM.

I have been using RL 22 with 180gr AB's in my 300WM since 2005. Hunt from +25 C to -35C, no issues for me here in Alberta with temperature sensitivity that I have noticed at the range or the big game harvested....hard for them to tell me when they are on the ground after the shot :mrgreen:

I have a friend that reloads the 168gr TTSX's in his Tikka T3 300WSM and likes it. He has taken a couple really large bull moose in upper NW corner in Alberta.
