I have this 18.5 inch shilen smithed by Dan Carey (who Shilen recommended.) Its a 6mm WOA..... heavy under handgaurd then .750 from journal to muzzle(threaded 5/8x24) I had it made while I was waiting for my bolt actin 6mm WOA. It is a VERY accurate barrel. shot several one hole groups in the 100 rounds I put through it. It has been fed nothing but 87 gr BTHPs with reloader 15. It comes with a matched PRI bolt for $375. No i wont sell them separate they need to stay together.
