I've only had one Kimber, a little 84M in 7mm08 and it both accurate and ready to go. Pillar bedded, adjustable trigger, the whole nine yards. I have heard of other Kimber users that complained of accuracy problems. I've never had a Tikka, but there are two in our group, the T3Lite synthetics, and they are both accurate and good triggers, but one has had magazine issues from the start.
I too like Mod 700s, but I just automatically spend money on them, replacement triggers, pillar bedding, blueprinting, etc. I will try out a factory barrel, but if it won't shoot after awhile, I'll have it rebarreled, then I usually go with a Shilen. There are many good makes out there and have used several through the years. For me, at this stage of my life, I prefer Remington 700 Classics and Winchester Mod 70 FWT classics ( mine is the older push feed) I like the Mod 700 CDLs, and Mod 70 Sporter Classics too. Lots of good choices out there, but I am more inclined to buy a used older model and have it tweaked. In my lifetime ( and I haven't tried them all mind you) any rifle is a "gamble", but I like to fool with them. I am undoubtedly "tainted" by growing up dirt poor and having to use junk guns until I got out of the Army and started learning more, making more money or trading up and I wanted quality over quantity. Its a good hobby we have though, it keeps us out of a lot of trouble! Good luck to you Pard!
