Dog, i understand what you're saying, i just don't agree. i've hunted with dots and cranking the turrets. for a carry gun shooting modest distances, i prefer the dots/ multiple crosshairs. most scopes will hold zero, but most variable scopes don't track very well. dots are the winner. when time is a little tight, dots are also the winner. most turrets that crank, stick up off the scope more, catching on the scabbard or anything. another plus to dots with lower profile turrets. i use a rangefinder, but a backup system is a nice thing to have. as far as changing loads/bullets. you'd be surprized how close different bullet trajectories are. i've shot 150, 165, and 180's in my 06 with dots and it's almost right on for each. again, i'm talking about modest distances, out to 800. precise aiming point, i'll give you that one, but i don't find it difficult to compensate for. if you can't line up on a deer at 800 with a 1/4 min dot, then you need to change something. again, i'm not talking about shooting at a gopher head at a mile. this is a big game carry gun that will be hopefully shooting an elk this fall in Wyoming.
with all that said, i am torn between just putting a MOA system instead of specific dots for distances for many of the reasons you mentioned. i will be using a dot/crosshair system rather than cranking turrets though. i havn't "pulled the trigger" yet!
