Can't go wrong with a pre-64 barreled action---unless the cartridge it's set up for just won't feed, extract or eject. It may not be such a sticky problem with the M70 CRF action, but I'd double check. Not a damn thing wrong with the cartridge performance-wise, but there again I'd double check to make sure I was willing to do what it might take to keep the rifle fed.
I'm here to give and receive knowledge, not affirmation or adoration. If you don't like it, mierda dura
