Just mentioning that if you could find old oxygen bottles, they make a very resounding and pleasant ding when hit, but you'll need to cut them in half. Cutting them at different lengths gives a different tone for each one.
So you cut the size kill zone you want out of steel and use that as a face plate and hang the bottle behind it with bailing wire.
KThomas, when are you going to come out and start shooting Field Target air rifle with the airgunnersofarizona club??? We are always looking for new friends that share our passion for shooting!!!!!!
From PCP's to ELR with big guns, I like it all and so does half our club. We'd have plenty to talk about!
