Well, I couldn't resist. I have to say that my favorite is my Rem 541S. I find, however, that when I'm going hunting I'll use any of my Remington bolts. I like them all, but probably baby the 541S too much and use my 580 single shot most often for hunting. I have a 580, a 581, a 541S and a 540X. I have a Clark Custom 10/22 that is very nice, but I reach and get my bolts most of the time.
Recently purchase a CZ452 in .22mag, but have not shot it enough to really bond with it. It is a very nice rifle and has a lot of potential. Some teething problems with the clip, but that is solved and it is 100% reliable now (if the ammo is). I have to say that so far I have had 0 failures to fire.
It is a bad thing when you have to pick one above the rest.
Bottom line favorite is the Rem 541S.
