Re: Springfield Armory scopes
Like most fixed power scopes, parallax will be set around 100 to 150yds. However, anything further will be in focus so parallax is not an issue. Closer targets may be blurry but who shoots under 150yds anyway (how about 90% of all hunters). Parallax at shorter range will also be so small that it does not affect accuracy.
With my experience with B&L products, optics should be very good. The tracking should also be excellent. Ian, let us know how it turns out.
The 6X24 4000/4200series scopes only have 26min of adjustments. I use Burris sig rings and inserts to shim up the scope so that I get to use all the adjustment. Like yourself, my scopes are "bottomed out" or shooting high at 100yds.
With a flat shooting mag., 20 to 25min should get you all the way to 1000yds with a 100yd zero.
Big adjustment only matters once you get past 1000yds.
