I've never had any problems with adjustment repeatability on ANY Weaver scope; from the old J series to the present day scopes.
Every Leupold Target model scope I ever used was also just fine.
The same applies to Bushnell.
Although I am still slightly paranoid about variable scopes, today's variables work so well I can't justify my prejudice against them. Windage and elevation adjustments are the same in either case.
The high end scopes may be better (given the cost, they'd better be!) but most name brand scopes will serve you well and you can afford more than one! Regards, Bill
