I had blood 2 but they got into swamps , I had an issue with my thermal I didn't know I was having till the **** scope till the scope almost fell off the base. I don't how to post videos on here or I'd show ya the shots . One was a head on shot at 200 video confirmed the cross hairs were perfect center mass . The dog fell backwards rolled and was gone . Went down look for blood and not a drop. So I knew I had P.O.I shift but couldn't find where went through everything and everything felt tight . So then I switched out rifles and the recoil of my 308 found it for me. I live in northern Wisconsin with alot of swamp and thick brush even with snow animals can dig in and make it tough.
