Friend and I are into our 2nd case of Quiet-segmented HPs. We depopulate rats at dairy farms. Thermals and/or NV. No trouble killing them to as far as we can make hits. 35 yds is the longest we've shot a rat using thermal. We do this stuff both inside and outside dairy barns. Cows don't give a crap....(pun)....about the noise. Mostly the 13 gr fragments do not exit, but depends on placement. Between 20 and 120 rats per outing.
