Re: .22 LR bolt-action rifles available in SA?
Would the Norinco JW15 make the budget list?

Re: .22 LR bolt-action rifles available in SA?
That statement is not the full truth. Which does not matter, since it is a pretty useless variable anyway.
Yes, most 22LR's will burn up all the powder in a specific cartridge within 16" of bullet travel, but likely much less than that. At what point exactly the powder burns out is actually quite irrelevant, except if muzzle flash is a concern. What is more important is at what barrel lenth the muzzle velocity is the highest. This may be hard to believe, but beyond some point the pressure behind the bullet actually decreases to the point that the barrel friction starts to slow the bullet down. This may (or may not) be bad for accuracy, but it certainly does not help to flatten the trajectory. If precision shooting is your game, then you will likely lean towards subsonic bullets, as the trans-sonic region tends to destabilize bullets and so ruins your rifle's fine accuracy potential. Having a barrel length that does not produce the maximum velocity may not be detrimental to achieving that kind of accuracy. So, generally the short (<16") and the long (>22") barrels are getting the best precision. The latter mostly with open sights, as a longer sight radius is advantageous here.
My point is, choose the barrel length for optimal accuracy with your specific load. Where the powder burns out is of very limited importance.
