SO is 60 grns you load ? What I have found with the old TC's is they perform well with 60 to 65 grns ,When I shot maxi balls or even Buffalo Bullets I found when I went above those charges things got squirrely . One round high ,one round left ,one round dead on. Later on when shooting round balls I experienced the same results. However I did find out that most of the TC's shooting rounds balls (at least the ones I own) will have another sweet spot somewhere around 85 to 90 grn. From the looks of your target I think you are in good shape. I haven't ran across any critters in Tn that could go very far with almost a 1/2" hole through its heart or lungs.. As long as you take good shots and limit the "Hail Mary" you'll do good.
