Hey, im new to slingshot hunting and i was wondering what the best type of ammo to use is?? ive heard that hex nuts are a cheap type of ammo but not sure how good they are for small game such as rabbits?? , also what are stones like?
While most any metal projectile will work, you want the heaviest metal in the smallest form. A lead ball is probably the best, and most reasonably priced option. Steel balls are also very good. You probably want to stick with spheres until you get good, as oddly shaped projectiles can effect accuracy.
Personally I'd prioritise mass, as the primary action of killing is blunt trauma to the head or torso. You want upwards of 7g, even for the smallest game; more for the hardy squirrel or a larger animal like a hare. You also need a level of hardness equivalent to metal, glass, or rock. Density is important too, but stone, rock or glass at 2.6g/cm[sup]3[/sup] is sufficient. Steel at 7.9g/cm[sup]3[/sup] or lead at 11.4g/cm[sup]3[/sup] makes sense if you plan to penetrate rather than bludgeon. Accuracy is at least as important as how hard you hit. Remember you need to be able to kill without causing unnecessary suffering. You need to be able to hit what you plan to, confidently and repeatably before hunting.
