I am shooting at my gun range and airguns only, all dedicated for BR. I know everything about airguns but never payed attention to firearms, so pretty much uneducated.
Friends in the club teasing me to get a .22 rifle, but my budget currently is not really in a best shape.
Also I am very anal for precision mechanics, I don't want to buy just anything.
Maybe piece buy piece to put together over a winter a good target rifle for next season.
I have a one-piece-rest for my airguns, I can duplicate one for the rimfire, so the butstock is unnecessary expense in my eyes, and also I like the chassis idea more.
Can you educate me please what parts to start with. The end result shall be to shoot up to 200 meters target rings (I have at my club 200-300 distances), and score the rings as well (I don't believe that just any barrel can do that).
The cautions pointed to by .22LRGUY are worth taking seriously. If shooting for precision and accuracy, there are limits to the suitability of .22LR. While there are disciplines involving shooting beyond 200 yards, they invariably determine results by the number of hits on a steel target. Shooting for score with .22LR is done out to as far as 200 yards, but most often it's at 50 and 100.
For a look at what shooters posting on this forum get at 100 yards, see the currently active 100 yard challenge thread here

There are over 30 entries in this challenge which counts an average of three ten-shot groups at 100. Only three of the entries have an average
under one inch. That standard is not especially easy to achieve.
If you intend to use a front rest or a one-piece rest, consider a BR-friendly stock. Chassis are often better performers with good bipods, the support with which they are most often paired.
A few questions about ammunition - what brand(s) do your rifles like? We know most rifles are brand sensitive for all kinds of reasons. Your experience might be instructive. Secondly, I remember a little sliding wedge rim thickness gauge advertised in the old Champions Choice catalogues. There was a hole for the cartridge, and a very carefully machined bar that slid over the base to measure the rim. In theory it was to sort the outliers for an even more consistent central tendency. It might have been like fishing lures - designed to catch customers. Have you ever examined your ammunition THAT closely?
Rimfire rifles are generally not ammo brand sensitive. In other words, there is no one make of ammo --
e.g. SK, Eley, Lapua, RWS -- that will always shoot better than all others. When it comes to target shooting, all match ammo makers produce batches or lots of ammo that will perform as well as the rifle allows.
Rifles with match chambers will often chamber match ammo more easily than bulk ammos or CCI SV, but that's because their chamber dimensions demand ammo that itself has more consistent dimensions. Rifles with sporter chambers will chamber all kinds of .22LR ammo, but a lot of .22LR ammo -- inexpensive, bulk, high velocity etc -- is not made for accuracy.
Sorting ammo by rim thickness is largely a waste of time and effort. Shooters looking to maximize performance with inexpensive ammo often try it as a shortcut, but very few, if any, serious .22LR shooters sort their ammo by any means -- rim thickness, weight, concentricity, or base-to-ogive length. The only sure path to improved results is getting good lots of match ammo.
The bottom line here, literally and figuratively, is that in .22LR shooting there are no shortcuts to good performance and that the only way to find best accuracy is to test different lots of match ammo.
