TQGEAR Professional slingshot ammo & catapult ammo 15mm plastic balls 500 per pack – Perfect Size & Weight - Better than 3/8 and 10mm ammo (Grey)

I needed 15mm for a project I wanted them for I did have a .6mm leeway but what these were dimensionally was way over that so bear that in mind.There maybe some out of that quantity at 15mm but do not expect many which is unfortunate as these were ideal from their hardness aspect. So if you are not bothered about exact size then these will serve you well

they larger than you think and most my catties dont have rifght size pouch foir them bit bigger than a marble. but shoot well and are fun when use say old black widow with the bigger pouch or just messingf around with the kids using a a fishing catty
