One I am stuck in rut - I think T7 is the best powder out there for me... It allows me to have the option of when to clean - it is not near as corrosive as other powders + it is reliable and consistent.
And I gotta tell, hunting in cold weather is a normal thing here in northern Idaho.. 20 below is not unheard of and 80% of the time it is below freezing during the late ML season. In the inlines shooting T7 with a 209, a 25 acp, or 32 H&R mag conversion is not a problem. When I go to sidelocks in that weather I do switch powder to T7-3f and a Dynamit Noble 107+ cap. It works - just fine..... + if you are really concerned you can use theShockey trick and wrap a hand warmer on the barrelabove the breech to keep the powder warm.
T7 gets my vote...
