Thought I did a post a about the slingshot I bought in the .22lrmor less thatead but I guess I forgot to post it.
I ended up buying a Trumark slingshot for around $10 from a chain sprorts store. I don't recall the model number but it was a basic slingshot with the wrist brace attachment. After reading a couple days on the net it seemed to really come down to buying a known name. The Trumark I bought has done a really good job so far.mActually better than I expected. It does have the simple folding wrist part and it seems to be holding up and working just fine. I took he wrist brace off at first but soon realized it really does help a good bit. It made my wrist sore for the first few days after using it but its not an issue anymore. By the time I broke the first band broke I was able to place dollar store marbles on a 1 litter bottle at about 25 to 30 with full power shots probably 8 out of 10 tries. I expect I will be 10 for 10 by the time a go through a second band. Oh and I tried some shots at around 25 yards and I was amazed at how close I could get. A few times I managed to study the curve of the marble and get within inches of the target. Never did actually hit the target (4" knot on a tree) though.
Good luck.. Would like to know what you come up with.
