1 in 9 twist for 1022

[FeuerFrei]

I am looking to upgrade the boy's 1022 with a new stock and a "subsonic" 1/9 twist heavy barrel.
I saw some good stuff on EABCO website.
Anybody have any relevant experience on how well the 1/9 works and or the EABCO or other vendor.
Thanx in advance.

My 10/22 barrel was replaced with a 1:16 twist, it gives fantastic accuracy with 40gr Wolf match bullets. What weight bullets do you want to stabilize with the faster 1:9 twist?

If you put a "subsonic" barrel on you will be limited to special subsonic ammo. The 1/9 twist is considered too fast for standard 22lr or especially high velocity ammo.

He probably wants to run the 60gr Aguila SSS's.

Follow up.
Just finished installing EABCO 1/9 twist heavy barrel and stock on son's 1022 yesterday.
Install was without surprises and after we loaded up several types on subsonic ammo we ran it without issue.
Everything (subsonic) works great in it. Sounds like a pellet gun.
Accuracy was very good. Much better than expected.
The barrel seems to stabilize 40 gr., 38 gr., 60 gr. ammo equally well...so far.
Longer range testing will tell the difference. Needs a better scope.
