well then.yesterday you answered your own question didn't you.
It seem's you and I have the same kind of values and ethics, last week my 10 yr old and I were shooting our BP rifles at 250 meters,open sights,off hand. didn't have a yote to shoot at but we were hitting the x sum times. Had a great time, we used up about 2 pounds of powder. It was fun,,one shot at a time.
I'll still be an advocate of "plenty of practice" an fresh powder though,
best wishes too you sir,truely,,,
If yer young son let game pass,like you say,,,,,,,,,
That's the sport..,well done sir,,well done!
ps. I got a few good recipies for camp cookin! Good food!
