Build?

I currently have a 10FCP-HS .308W and an extra Lothar-Walther 6.5Grendel 30" barrel + the PPC bolt head for it. since I have 200pcs of Lapua brass, Forster dies and an abundance of 6.5 bullets it seems a shame to not have another rifle.

What I am thinking of doing is building a dedicated 6.5Grendel rifle for target shooting and prairie dogs.

What would you recommend for an action, where to get it, etc. Stock?? dedicated bench or a tactical so a bipod could be attached?

OR...sell these and start over?

Thanks
