Has anyone had trouble with berger varmint bullets not killing? I shot a coyote tonight with a .243 80 grain berger varmint at 581 yards he did the spin dance for awhile and the trotted off not limping or humped or anything. Found a little blood but never did find him. Also shot a mule deer doe at 400 with my .270 shooting 140 grain vlds and she jumped and kicked then ran off. No blood and never found her. Last I saw she was on private property still going good. I shot 2 antelope with the same combo both about 350 yards and they tipped right over. I love my bergers just having some confidence issues I guess. Am I doing something wrong or what?
