Hi Folks, It's been a million years since I picked up a slingshot. I just recently bought a Barnett Striker 9 as a "get back into shooting" slingshot. I've already swapped out the bands for a "red" set which are much more powerful but I was wondering if anyone had some advice as to improving the bands and what size ammo I should be shooting out of it because the hand slap is brutal. I'm holding it in a pinch like grip and not by the handle alone so any advice would be helpful. Thank you in advance.
