You should know that in rifles the bullet will be below the line of sight at the muzzle. I will rapidly climb and cross the line of sight . Most rifles , reguardless of caliber , do this around 20-30 yds out. From then on the bullet is above the line of sight and climbing until 50-75 yds out , then will slowly drop. Your sights are made to zero the rifle in this drop phase . !st is 100-150 yds , second is 200 , third is 250 and forth is 300.
If you shoot really close up , you will have to play with the elevation settings to find the right ones even if it's dead on at the longer ranges.
Of course , if it's not sighted in , anything goes.
It's great people help each other out here.
Enjoy , Chris
