Take a look at olympic grade 22LR target rifles from Grunig, Bleiker, Waltlher, Feinwerkbau, Anschutz etc, barrels are generally the same dimensions, heavy bull types and about 26" in length with additional sight extension tubes on the end. This is where the best accuracy can be found although for most people a 16" barrel will be just as good as it won't be the limiting factor. (look in a mirror to find that)
If you want to take part in competitive 50m shooting then guns (well mostly the stocks) also differ between prone (including 3 position) and benchrest so know what you want to do, also many target ranges only allow single load rifles so no magazines (this is actually an ISSF rule for prone/3 position)
Second hand might be a good option, check out places like Target Rifle South Australia, they usually have old club guns for sale which a still very servicable and accurate.
