Re: 6.5x47Lapua Necked to .22 Cal ?
I built one and get great accuracy and an easy 3,200 fps out of 80 g JLKs. It is a very easy round to load for and had no problems. About 1,200 rounds and no loss of accuracy.
For dies I just used Redding 6.5 x 47 Lapua bushing dies and stepped the neck down in three passes.
