I gave a few 303 British to a friend and he gave me 100 41 cal XTP I can load in 41AE. I don't have a 41 mag anymore. I thought that was nice of him to do but when I got home I found 200 of the same bullet in storage. That's OK as they will all shoot. I did load 3 loose 41 I had laying around and I found a partial box that needed filled up. Boy we are having fun now. Craig
