Don't feel to bad Rich. You took one for yourself and gave one to the wild game. Nothing was wasted. Took and gave all at the same time so to speak.
I feel bad if one gets away (happened two times) because it makes me feel like I'm a poor shot or made a bad judgement in taking the shot.
The first hog I ever shot got away. It was a clean 20 yard side shot with 20ga buckshot on a big sow. I will never use buckshot again. If was a head or neck shot it may have worked.
I gut shot a med size sow with a 45 colt trapper. You know that was a bad idea. That was the only hog that ever charged me.
I've let lots of pigs pass if I can't make a good solid neck shot. It makes me feel good about my abilities and judgements when hunting. I'm sure the coyotes and buzzards don't like it
I also like to hunt hogs on the ground. Go in the brush where they bed down for the day. Things can get fast and exciting.
Glad you had a good hunt! Sounds like you were at a nice place up there in north Texas
