Mac, Is that a DWM made in Berlin or an Argentine made action? 1909's are a darn good action. I would build a 257 Roberts on it. No mods needed other than barreling it up. A 30-06 will fit with some massaging. Some of the Argentine built are a bit prone to being soft in the recoil lug area. Not a danger but not good for long hard use. Build it up.
