I am using a 6.8 with Hornady 120ssts. As far as penetration it passed all the way through head.
My buddy's gun is using a 223 and reloads 62gr Barnes TTSX. His shot hit heart and didn't pass through. I am impressed with the Barnes on the 223, like with any bullet shot placement is key. Need to get him to reload some for me.
Okay, cool. Didn't see a lot of exit wound damage that I was expecting, but that happens sometimes.
I'm really surprised of the # of 200+ pound boars there are out there. Cant imagine them growing that fast. I imagine in less than a week another one will come looking for some trouble.
The 200 lber we shot on Thursday night still had not erupted his 3rd molars through the gums. In fact, they were just breaking through the bone. That puts the hog at less than 18 months of age. They really can and do grow very fast.
