I went to a public range today looking to fire some test loads. This range has been fairly empty of others, when I’ve been there before. The place was packed with people sighting in before their elk season tomorrow. There was an open bench, so I started setting stuff on it. Then set up my rest and mat on the cement next to the bench. People were all noticing, and coming up asking questions as I pulled out an F class rifle. I spent an hour just answering questions, and a lot about their own gear. Then a guy came walking up from far end of line. He was asking about his rifle not shooting his newest ammo. He said that he bought some ammo with round nose bullets vs pointed, and they don’t shoot. He started with the firing pin didn’t appear to be striking primer. I asked him a couple questions, then he says that the extractor won’t hook and remove the rounds. I asked if I could see his ammo. We walked down a he shows a box of 7x57 ammo. Then another box of 7 Rem mag that did work. I showed him the difference between the 2 cartridges, and why the one won’t work in his rifle. Then showed him the cartridge wording on the 2 boxes. Totally different rounds.
