So im going to be purchasing a green mountain barrel shortly for my 10/22 and was wondering what length i should get? Ill be shooting mostly from a bench at 1-2-300 meters. Any thoughts? pros cons? they offer them in 16-18-20" lengths.
What length barrel?

No answer but I was thinking the same thing. Are there any choices in twist as well?

200 to 300 meters from a .22?
Ya i know not the conventional use for a .22 but my goal is to hone my long range shooting skills with the .22. If i can get a handle on correcting for wind at 2-300m then when i take my .308winchester out to 6-7-800 meters i should have a lot easier time correcting for wind. Atleast thats the plan anyways. Obviously i wont shoot the .22 at 300m with 30km/h shifting winds because ill never be that good.

It's not the wind, its the trans-sonic zone where the bullet drop to subsonic that disrupts the flight path. While still dangerous past 4-500 m (at about 500 ft/s) the accuracy falls off past 100-150 m.
Tell that to all the guys with 1/4" groups at 200 yards and 1/2" groups at 300 yards using a .22 and match grade ammunition.
You can get subsonic ammo to eliminate the trans-sonic issues as well.
I realize the bullet will transition to subsonic on its way out to my target no matter what barrel length i use so i guess my question really is should i get a shorter barrel to increase velocity so that it crosses the "trans-sonic zone" later or a longer barrel to slow the bullet down some so it transitions to subsonic sooner. or is it not going to matter because either way its going to reach subsonic before i reach my target.
Or use standard velocity ammo and stay subsonic all the way out from the muzzle. I would pick the one that balances best with your stock and scope set up.
