[QUOTE="davewilson, post: 33877, member: 4491"] i used to spend sept till mid dec in central saskatchewan chasing deer sized critters.i used to wonder the same thing except i was more concered with point of impact rather than group size.the cold weather can have an effect on POI.the colder it gets,the more it can affect the gun and i think the difference in burning temperature of the powder has the least to do with it.my temperature range i hunted in was +40 to -40.i always sighted in when the temp was in the 0 to -15 range.i was convinced the gun shot a bit lower in the colder (-20 to -40) temps.i used 1 more grain of powder in my 30-06 when it was -20 or colder.i don't know what temperatures you're talking about,but i've seen a lot of guys come into camp(i helped most sight in)and blame the handling of their gun from the air lines,on a POI change when it wasn't that at all.it was the temperature. my advice is to throw your gun and ammo in the freezer for a couple days and see where it shoots when it's cold. that 1/2 moa difference in accuracy is BFD compared to where will it shoot.
