Re: Is this a scope issue
While this can be caused by the scope, it's probably low on the list of causes. In my experience several things can cause this type of dispersion:
Shooting problem: Trigger break, sight picture, hold consistency, rest consistency.
Rifle problem: Bedding, loose scope mounts, defective scope
Load problem: Seating depth with Berger VLD's, powder, bullet, case prep(runout)
The only way to figure it out is to isolate the issue. Most importantly, don't change too many variables at one time. The heavier the recoil compared to what you are used to, look to a shooting problem. If someone else set up your rifle, look to a rifle issue, especially bedding and mounts. If you are using VLD's, check seating depth or try a standard bullet. The scope is the easiest, try another one. iMHO.
