My neighbor/fellow shooter....goes on binges where he becomes obsessed with what bullets expands the best. Internet forums, youtube, he looks everywhere for that magic bullet. The "thing" he keeps coming back with is "No, that bullet doesn't expand when it is shot through multiple layers of denim" or "Yes, that bullet does well in the denim tests." I can't help but laugh thinking that this would be a good valid argument if we are ever attacked by Canada, lol. Yeah, yeah I know.....it;s in the FBI protocol tests.....I still just can't remember the last guy I saw wearing a denim jacket, much less multiple denim jackets.
