Don’t gwt me wrong. These are very useful for training. But only for like 100. As someone That works with Firearms, Throwing knives, Crossbows, I can honestly say you only need about 100 training routes because for every training round you should have a round that is much stronger to equal you out so that you know what it feels like to shoot for example a metal route or we’re talking a crossbow a real hunting bolt I guess if you don’t know what it feels like to shoot it then you’re gonna miss out and you gotta learn on the fly….
