    so today I went shooting for the first time in about 6 months...
    maybe more.
    Dug out our old Remmy 521-T, .22 with Lyman peep sites.
    Was shooting .22 CB caps in it...and well...

    Is this the result of not shooting for 6 months, or is match ammo
    actually more accurate then this?
    (squares are 1/2 inch blocks)

    on another note...
    sometimes it just feels good to go shoot a .22 bolt...I need to go more often.
    It's good for the soul.

    oh yeah...I might add that I was shooting at 20 yards because originally I was shooting at about 75 yards and well...
    .22 CBs are a joke at that range. They were dropping well over a foot.

    I know almost nothing about the CBs but ammo does make a difference. I've not seen a group open up to, what, 2.5 at 20 - 25 yds in because of ammo though.

    Match ammo does print better. But CCI mini-mags print almost as good for my .22s

    Sometimes I shoot really well after a dry spell. Most of the time not & it takes a bunch of rounds to get better.

    When returning to the range after a while I'll study the NRA book on Basic Rifle Shooting and take it with me to the range.

    In my experience, CB's suck big time when it comes to accuracy. I'd actually consider that a pretty good group considering your ammo.

    My CZ452 does very well with cheap American Eagle ammo. 1.5" groups at 100 yards is pretty typical.

    well I may have to
    A) shoot more
    and
    B) buy more ammo.

    bummer huh?
    I was using CB caps cuz...well...real long story.
    Neighbor problems is a good way to sum it up.
    Wish I had a Class 3 permit so I could stick a silencer on that ol'
    bolt action for some quiet target shootin. Hence, resorting to CBs.
    I may just try some nicer ammo tho at the same range and see what
    happens. If my groups still suck..well..then I know I need to burn more
    .22 rounds. :D

    It sounds like what you need is a good air rifle. Unfortunately however, good air rifles cost considerably more than their rimfire counterparts.

    I've heard people report getting good accuracy with .22 CB's before, but I've never come remotely close to achieving it myself. My groups with CB's are about the same as yours and they really start to fall apart with distance. You might try Aquila SSS rounds as well. They're about halfway between a CB and a .22lr when it comes to noise, but they pack the same energy as a .22lr. Accuracy with them is mediocre. Up close they do OK, but they are too long for the rifling in most .22 rifles and they start to keyhole at longer distances.

    I may just move my shootin spot to the other end of the property
    and use LRs. Mebbe use subsonic rounds...wonder if those are
    any good?
    thanks for the help!

    22LR target ammo is sub sonic by design. The shock wave as a bullet goes back below the speed of sound disrupts its flight. Ammo makers load their target ammo below this point to prevent accuracy from degrading. If you are looking for a accurate load with out the noise level of the LR maybe a 22 short target load would be a choice in stead?

    huh? I thought LR was just over the speed of sound? cuz they sell
    ".22 Subsonic" rounds and then they sell .22LR rounds from the same company? Or are they both subsonic and it's a marketing gag?

    Sub sonic rounds would do much better for groups for sure. Many match loads are sub sonic.

    Your situation reminds me of when I was a young kid and we had a garage/workshop that was about 50 ft long. We made a sound dampening box out of wood with ceiling tile baffles to deaden the sound of shooting .22LR in the garage. It worked OK, not near as good as a silencer but we never heard from the neighbors. That was in a urban neighborhood in south side Houston!:D

    You may try a cheap experiment with a large heavy cardboard box and some sound deadening fluff inside to attenuate the sound enough to suite the neighbors. Small hole through two sides to view and shoot through. It's not mounted to the gun so there should be no problems with class 3 requirements. My opinion, fwiw.

    I noticed you shot this in the prone position which is comparatively steady but you really should give this ammo a try from a solid bench using either a machine type or sand bag rest. That will throw out some user error and give a better picture of the quality of the ammo.

    The LR loadings cover a wide range of velocities. There are 22LR sub sonic, std velocity, and hi velocity loadings, plus the "mini mag/Viper types. All are Long Rifle cartridges, target loads are mostly sub sonic in velocity.
