I'd say pretty good. Shot 2 antelope last weekend, lasered at 342yds and 387yds. 1st shot hits on both. Heart on the 342, spine on the 387.(misjudged the holdover a bit on the second) BRNO ZKK 601 30-06, 165gr Ballistic Tip, 58.5gr IMR4831, old Simmons 4-12x40AO, 200yd zero, prone unsupportted, light wind from 4 o'clock, sun overhead. Shot one earlier in the day between 200 & 300. Didn't have time to laser that one so chose a compromise POA and took it through the lungs above the heart. It must have been closer to 200 than 300 judging by the POI.
