That's what I'd do if I were to reload it. In no hurry to start another calibre. Don't shoot it enough.Lee comes with .308. You can buy the .311 pin from Lee they ship to Canada (or elsewhere if you can find it). While I was waiting for pin from Lee I just switched the .311 pin out of my 303 Brit dies.
I believe that RCBS 7.62x54 dies comes with .311 expander but I couldn't find a set anywhere.
