twist rate for .22lr SSS or any subsonic ammo?

[rancilio]

Hello,

I am considering another 14 or 15" Encore barrel. Does anyone have experience with a .22lr fast twist (perhaps 1 in 8 or 1 in 9) for SSS or any subsonic ammo?

How would a fast twist .22lr do with high velocity ammo?

I intend to put a suppressor (to also use on .223, .243 and a 6.5x55 barrels) on it in a few months once I decide which can to purchase.

Thanks,
Matt

Green Mountain barrels make them for the 60gr in a 1:9 twist. You might find one for sale at rimfire central or more information.

Tried some yesterday in my CZ 452 (1:16). They did not stabilize. I wasn't expecting them to after some research but I had to try. One key holed about 6" left and 3" low at 25 yds.

Ive got a cut down pocket rifle kit for sale with a 1:9 twist. check it out under my SN. GM makes good barrels though.
