Bannockburn,
I have both; the Ruger was puchased new in 1978, and the 597 I bought for my son a few years ago (his choice). My 10/22 is extremely reliable and accurate, even with iron sights; eventually I mounted an old Weaver K2.5 on it, and its still putting them all in the ten ring, provided I do my part as well. Preferred ammo is still CCI MiniMags, though I have also been getting some really great results with Wolf Match Target. My sons 597 is another story. I can't report on accuracy because it jams so frequently, its difficult to have any sort of consistency with it. I have tried all the fixes for it, including the reworked magazines and tightening down the op rods. Nothing helps; what adds insult to injury though is the fact that it does the worst (FTF and FTE), with any Remington brand ammo. Go figure.

Wow, that surprising. I run the cheapest ammo I can find at walmart through both my 10/22 and my 597 and they both shoot great. I buy the 550 round bulk boxes or ammo at wally world and don't have any trouble.
