Re: best barrel length for a 22lr
i've heard alot about adding weight or a barrel tuner to the barrel, finding the sweet spot (as far as where the best groups are appearing) and then trimming it there. although i never did it myself, it sounds like the best way to determine the best length for YOUR rifle. as rifling and the quality of the barrel differs from manufacturer to manufacturer, determining the length of the individual rifle seems to be the best idea. sort of like the .22 ammo performance principle in individual rifles.
most likely the use of standard velocity and high velocity rounds will have an effect on length and will differ between the two. but then again, the shorter the barrel, the less velocity you'll get from the HV unless you can get that sweet spot where the powder is all burnt up and will equal the SV velocity.
another theory is that the shorter barrel reduces barrel whip / harmonics, which increases accuraccy.
however, others preach longer barrel for sight radius (open sights) and that a longer barrel stabilizes better.
can't semm to find a definitive answer other than the discussion being a pissing match and going off topic.
i would search some benchrest sites, as those guys have the whole mechanicals of rifles down, and do some pretty extreme things to their equipment. maybe there is a consensus on a general length.
obviously grouping shots or consistant performance is the ultimate goal, but as far as the goal of reading wind, i'm thinking you'll be GTG by just using what your set up is now.
couple of links to the subject, but generally it becomes a pissing match rather than hard evidence:

seems like 16" to 18" is the general idea, but still have not found the "hard facts" that would make me want to start chopping my barrel.
if you REALLY want to figure it out, i guess you can buy a beat up POS .22 and start taking off inch by inch and compare results on paper and crony using both SV and HV ammo. then apply the length to the "good" rifle.
that's probably going to be the only real test, and a true answer. i'm sure someone somewhere has done it, i just can't seem to find it.
