Do you use a scope level to keep your rifle level?
Do you use a scope level to keep your rifle level? There are quite a few different ones available now with various mounting methods. A slightly canted rifle will cause a bullet to impact way off course at significant distances.
Canting can be a problem even with a flat shooting cartridge such as the 7mm Dakota that I use. I fire a Cauterucio 176 grain VLD bullet (BC = .750) at 3,150 fps. In Montana next month at 2,000 feet and 40 degrees, this bullet will reach 1,000 yards in 19 minutes of adjustment. That's pretty flat.
Now picture a 6 degree canting error. That is one minute on a clock. Stand in front of a clock and place a long straight edge up against the face of the clock. Place one end of the stick at the clock's center and rotate the other end until it rests on the "14 minutes after the hour" position on the clock. That is all the cant error it takes to be 6 degrees.
According to Loadbase ballistic software , my bullet will be off at 700 yards by 12 inches to one side and an insignificant amount low.

Gotta have it!
Jesus Christ the same yesterday, and to day, and for ever.
Our Lord Jesus said that as it was in the days of Noah and
also as it was in the days of Lot so it shall be in the days...
It's happening again!!! God sent to us His prophet, and His Word
to this generation and we once more are rejecting it as was prophesied!!! ---> As promised, God Sent His Prophet to us!
