The reason I am asking, is that I shoot a vertical , and own an x-bow. so now I have thought that when buying broadheads,( I know they make x-bow heads and that you should not use regular heads in an x-bow. ) I started to buy x-bow heads, to use in either. but lately, I have heard of a couple of myx-bow buds complaining that their mechanicals opened on the shot? I am curious if this is common, or and excuse, ( I have a few) for a bad shot?
