The Leupold M4 line of scopes has become quite broad. To get the wide moa range (140), you have to go with one of the fixed power (16x usually). The variables are nice, but something about variable objective limits the end to end moa adjustment. The M4 variables tend to have 70 to 90 moa at the top end.
The other way around the scope adjustment issue is just to push a bigger bullet faster. For instance the 338 caliber 300gr Sierra matchking, with a 3000fps mz velocity only has around 22 moa of drop at 1000yard with a 100 yard zero. 22 moa is within the reach of less expensive scopes than the M4.
How bout this?
