I've given up on trying to get my hands on anymore Fed GM215 primers. I'm down to my last 200 primers. I use them in several different loads and calibers and realize there ain't enough to go around. I also recently spoke with a friend in Minnesota who said he talked to a Fed rep who advised it'll probably be latter 2014 before anymore of those primers make it to the public. As such, I went ahead and picked up a 1000 Winchester mag large rifle primers. I've never reloaded these primers before. Does anyone have any opinions. I'm trying to decide which calibers will get the Winchesters and which "one" I'll save the Federals for...
