I'm still new to firearms and in fact I can finally pick up my first gun in 3 more days. I understand that my local range sells 2 types of ammo: Factory and ammo that they collect from the range and reload themselves. The reloaded is much cheaper and I would suspect better for target shooting because of that.
But my question is, is there any ammo that is "bad" for the gun (other than the wrong size of course)? If I'm going to be putting thousands of rounds through a gun, I don't want it to be causing excessive wear on it, if that makes sense. Also, just out of curiosity, is their reloaded ammo as strong as factory ammo or is it a dumbed down version? Thanks.
