What the Heck are These?????
Was given these rounds. Have no idea what they are for. They are made from the parent case of the 30-06 WWII rounds. Overall they are 1.668 long with a case diameter of .468. They have what appears to be a 45 cal gas check crimped into the mouth. The gas check is cupped and has a small ridge inside the case mouth. They are full of shot. Checked all my reloading books and found nothing even close to these. Hopefully, some of you can shed some light on these things. Will appreciate any and all info you may have. Thanks
