Shot in it all day yesterday with a 10+ mph north wind. Just made a cold bore shot at 500 the day before with a 20 mph south wind. Weired the winds can be that strong out of both directions one day to the next.
But in the cold you had better be able to get the density altitude and temp factored in prior to your shot. 80F DOPE aint the same as 40F DOPE.
Question for the ignorant.... What difference does it make between 80 degrees and 40 degrees?
Cold air is dense air. Dense air causes a bullet to lose velocity more rapidly. Tuesday I was shooting a friend's 308 Win to 800 yards. I had DOPE from 80 degree weather. Well, to get my client to get hits at 800 yards I had to add .4 Mil to the elevation. Bullet slows down in flight, bullet falls to earth more, raise elevation in the scope to compensate. Keep in mind 308's are very sensitive to this outside 500 yards. A 6.5 Creedmoor or 7-08 will hold up better to about 700 then temp becomes more of a factor. That's BC and MV for ya.
