Man, I can hear the jokes now, longer, thicker and harder.....

I am sure they have been done to death and I am sure it has been asked before but the search engine here is only 1 step up from useless, so please forgive me if I am asking a question that has been asked a dozen times. I am also sure it is a hotly debated topic with many points of view I welcome all.

What do you think is the ideal length for a 10/22 barrel? For velocity, for accuracy?

At what length do you start losing pressure/speed?

I have a Dlask 16.5 bull that I love but the gun seems short to me, I want to go up to a 20" on my second and rechassie my first to a taticool, but am I hurting myself with a 20" barrel as the second one will be my 100 yard + toy and I think of steel as harder and will hold better but is very heavy, how much will I suffer going to aluminum?

Again, sorry to rehash old topics and thanks to all for your input in advance.
 
I was just doing some reading on this, as far as what I have come across, after 16.5" the muzzle velocity begins to decrease. However, it is the chamber that makes the most difference. A barrel with with a bentz chamber, such as a green mountain will be much more accurate. I have a green mountain on my 10/22 and a Tactical solutions on my SR-22, the GM has a bentz chamber, the TS does not. Both are 16.5" barrels but the GM is much more accurate. If you want to know if you have a match chamber try taking a CCI stinger and by hand place it in your chamber, if it is a match chamber the CCI Stinger will stick out quite a ways. If it goes in just like any regular .22 then you do not have a match chamber. CCI Stingers are just a hair longer than a regular .22. Make sure your bolt is locked open when doing this and NEVER release the bolt while the stinger is in the chamber. Stingers are not to be used in a 10/22, even says in their owners manual. However, you will not be firing this bullet and are just using it as a reference. Anyways, I hope this helps. Rimfirecentral.com has many articles on this if you are curious.
 
FWIW I notice very little loss of velocity between my 16" ruger barrel and my 12.5" Dlask. Around 100fps with bulk ammo... The difference with boutique ammo like stingers and velocitors is much greater though, something like 250fps loss with stingers.
 
Depending on barrel and ammo details, maximum velocity is achieved anywhere from 12" to 16" with standard velocity (and the basic "high" velocity) ammo. There have been threads on here and Ballistics by the Inch did a test as well. That said, many target rifles have 20" or longer barrels. While this won't give peak velocity, it does seem to contribute to more consistent velocity and it helps keep the velocity sub sonic, both of which contribute to accuracy.

If you want a real tack driver, going to a 20" barrel certainly won't work against you. As for the thread title, that's what she said!;)

A 12.5" barrel is sending the lead out at almost the same ratings as on the back of the box of Champion 525rnds-bulk ammo.
 
I remember reading about a fellow who took a .22 rifle and cut a half inch off it until he started to lose velocity again.
He was averaging standard velocity loads and found on that rifle 13.5" was optimum.
