Hum. Maybe I _was_ a better than average shot then. Barring initial problems
(breath-control with the rifle, to keep the ups-and-downs under control) I
could drop 45-50 rounds into a 3-4 inch circle at 250m, with a weapon NOT
zeroed for me, and _without_ my glasses. First try with a rifle, too. <g>
Give the newbie a prize?
OK, so I missed the target completely with all those shots, by about 18". I
still had a consistent grouping, inside a _very_ narrow area, and missed by
less than 2 feet. All at nearly that "maximum practical range" of 300m, and
as a nearsighted utter newbie lacking his usual glasses. :-)
And yes, I had forgotten about the acceleration effects and only dropping
_half_way. I had not learned, though, about any _upward_ rise of the bullet
(my military stint was exceedingly short). Still, knowing the range is a big
part of that.
Maybe instead of a DOT, the firer sees a thin LINE tracing the proper
ballistic arc? Since it would be relatively easy to input (during
installation) the ballistic parameters of the weapon, to the Smartlinks
memory. :-)
That would also make firing with a bow more accurate, since as you raise the
bow up, the 'link recalculates the arc, showing you a different "trace" ...
though if smartlinks worked that way, they should get no additional benefit
from Tracer rounds. :-)
