Now I am going hunting in Saskatchewan in the end of November, the Temp will probably be around 0 farenheit if were lucky, the elevation will be 1650 ft average, by how much will my drop be affected in moa? And what calculations do I need to do to get to correct my drops?
I am not sure what the baro pressure will be there? Or is that a standard that depends on altitude?
Cold temperatures will have the most effect because of the ammunition.
Most people just keep there ammo in there pocket until time to use it unless you have time
and a place to verify the zeros.
This is a good place for the detachable Magazine. you can keep it in your pocket and then just snap it in the rifle just befor the shot.
I allways recomend checking the zero at the site to be hunted but this is not always possible
so try to maintain conditions that are similar to those at home.
One thing to check before you go into that kind of cold weather , Remove the firing pin and
remove ALL grease and oil from it .It wont hurt the rifle and it will assure that you dont have
grease and oil stiffening up and preventing the rifle from firing. (IT Happens all the time).
Good luck and stay warm.
