While I have not had a bad experience shooting in my back yard, after only a couple sessions I realized I was stupid shooting field tips back there. I have read some posts on this subject. Even if I did not hit anything or anybody, just the thought of retrieving an arrow from a neighbor is a horrifyingly irresponsible thought.
So I bought these 100 gr rubber tips. Even though I knew it would not be too good, I tried one in my layered target. Do I need to say it was an undesirable result? Stuck tip and obvious mis-use of the target.
Then I hung a free swinging 3 ft by 3 ft piece of heavy carpet from a frame, with a paper target on it. Someone else had to watch to tell me where I hit. Then for the funny part . . . my son tried using a rubber stamp ink pad to mark the hit. Dunk the tip in the pad and shoot. It works better than I would have thought.
I really don't know how much damage these tips could do. I know I have been very impressed with the energy you can develop with a bow. The neighbor who lives in the direction we shoot is also a shooter and is comfortable with what I am doing. He is now shooting these my direction in his back yard.
Any thoughts, even if you're going to tell me I'm still not very smart?
