I looked for a sako a7 338 federal in stainless to modify into 338 rcm but haven't found one yet. I am curious to see if the rcm will feed out of the sako a7 magazine. Bolt face has enough meat to be opened and a 338 federal or 7mm-08 could be rechambered easily, I would think.
Should give 338-06 or 280 performance in light handy rifle.
