    To anyone with a 22 with a 1:9" twist (as for 60gr Aguila):

    What kind of accuracy do you get with 40gr LRs?

    I have never shot or heard of a 1 in 9 twist in a 22 LR (They are normally 1 in 15 +).

    But I did not have good luck with the accuracy of the sub sonics, so that may have been
    the problem. (to slow of a twist rate).

    The lead 22 bullets work best in a slow twist because of the tendency to shear if twist is
    to fast. but the jacketed bullets would probably shoot OK in a 1 in 9 twist barrel.

    I will be interested to see what others have to say.

    J E-
    Thanks for your reply to this post as well as my June 4th post (Switch Barrel .22s)

    Other people might not have a lot to say, as my shooting interests are sorta out in left field!

    If you scroll down this page, you will see where others have had custom 1:9" barrels made for the 60-gr Aguila rounds.

    I have heard from Redmann Reboring to say that he can probably reline a Marlin Papoose barrel with either 1:9 or 1:24. (He needed to see the bbl) The latter would be good for .22LR CB Caps, which are quiet. I never could get the CB Caps to group well from the std .22 LR barrel, which, as you say, is most likely around 1:15. I do not think it is the rate of twist so much as the way the CB Cap lies too far behind the leade of a regular .22 LR chambered bbl. The std .22 LR (40 gr) should sit well in the leade of a rifle chambered specifically for the 60 gr Aguilas.

    I think RUGER should offer 12" bull barrels for their Charger pistol. Perhaps in different twists,
