Where did you get the brass? Is it actually .275 Rigby or 7x57?
I think all of Hornady's new 7x57 brass is headstamped 275 Rigby. Check Grafs, Midway, Midsouth, etc.
"An archer sees how far he can be from a target and still hit it, a bowhunter sees how close he can get before he shoots." It is certainly easy to use that same line of thinking with firearms. -- Unknown
