As long as we have no wind (fat chance!) or relatively steady wind, 1200 yds is also our maximum reliable range, requiring 13.1 mils of elevation, but easy hits on full-size IPSC steel, though any further gets unreliable (presumably transsonic instability)—20" Krieger 1-8" twist, 123gn Lapua Scenars, 2644fps MV, 105°F., 1909' density altitude
