I have a 742K that I bought in like-new condition some 8-10 years back. With a K4, it shoots about one MOA at 100 yards. I've only put maybe 40 or 50 rounds through it, but I've had zero troubles. It might be a little picky about brand of ammo; at least it didn't like a WalMart special deal on Win. 150-grain Silvertips; but, neither did my pet bolt action, for that matter...
I'm not particularly sensitive to recoil. At any rate, it's certainly no worse than any other '06.
FWIW, Art
