Excellent shooting off-hand with the Trail XL!
Those 3 must have been youngsters to hang around after the 1st one got shot, and only 10yds away! That's ok they are just as fun to shoot as the adult ones which are more challenging. I took 5 of them that were only 2-3mos old and another 4-5 or so last year that were about 4mos old towards the end of the summer. They are not as experienced and will pop their head up again after spotting you because they are curious and don't know about all the dangers yet, or they are too hungry and are not thinking like an adult, and want to go back out to eat sooner than later.
Most young ones born in the Spring hang out together until the end of the summer and split up usually by the middle-end of September to get their own burrow. Unfortunately I have shot the last 2 females this Spring and now a couple of big males that I would spot around the neighborhood (and 1 in my backyard last weekend) have moved away to find females. That's the problem when you shoot the females. You lose the males too who will travel several blocks in search of females and they usually don't come back. They hang out where the females are at. As you can see I like having G-hogs around and didn't mean to exterminate them. It keeps it interesting around the yard, the stalking, adrenaline and all that
And don't believe Jeff. He is not hunting because he is waiting for all the G-hogs to give birth and the young ones to grow a little and then he 'll go after them with no mercy

I on the other hand do not have that kind of will power, and shoot on sight without thinking, hehe
Looking forward to your next barn hunts!
