Hello, i am looking at getting a rifle in 22br. I was looking at getting a rifle from er shaw. I called them asking about if it was a no turn neck. The fellow i talked to seemed confused by this question. He said it was a 22 rem br specs, no turn. I looked up 22 rem br http://www.6mmbr.com/f/Sierra_22BR_data.pdf and it looks like its a .246 neck. The way i understand it with blue box lapua 6br necked down i would need a .254 neck. Is this accurate? I asked five times what the neck was on there reamer and got nothing. Thanks
