Side focus?

For me, it seems yardage wise the front focus is more accurate. Side focus scope numbers are always a bit off from the ranged yardage. Having said that, if you are really savvy at range estimation without the use of a range finder, I find the front focus faster than using the side focus. 

I always orient my scope cap to pop up at 12:00, directly above the top of the scope, for my most used range of 40 yards. That means the scope caps hinge is at 12:00. I know from the orientation of the scope cap a twist left to 11:00 on the caps hinge puts the scope parallax adjustment at 50 yards and a twist to the right to 1:00 is really close to 30 yards.



Side focus dialing I must be looking thru the scope to use clarity to get me my desired range(if I already know the range without the use of a rangefinder). I do not rely on the numbers to dial for range. 



Spend a few hours at the local high school football field, and you’ll get range savvy yourself.
