    I took my new 10 22 "takedown", with installed 'scope, to the El Campo Range one afternoon for sighting-in.

    At 74, I had never experienced sighting-in difficulty with any rifle, before this. But at this age, can't see plain sights; must have optics.

    Hot day, using gun sled, would get all in 1" @ 30 yards.

    Lean unloaded rifle against bench while reloading mags, rifle back in sled, x-hairs on center, shots 10" low and left.

    Went through this several frustrating times, before deciding to send litle rifle to "expert".

    Expert had similar difficulties.

    "Guru's" were consulted. Their diagnosis was that the barrel attachment knurled knob "nut" felt tight to hand, but wasn't fully tightened. Cure was to use protected jaw pliers to fully tighten; problem disappeared.

    I am posting this in hopes of helping others who may experience this peculiar problem. You should keep "protected jaw pliers" with your "Takedown" 10/22.

    Plan to try rifle on squirrels at my little bayouside swamp this Fall.

    thanks for the heads up on a potential accuracy problem.

    Though I don't understand what was going on.

    Sure, that knurled know allows the barrel to mate snugly to the receiver

    I was just messing with mine.
    Given the fact that both the front and read sights are on the barrel I don't see how that could make anything more that a minuscule impact on accuracy.

    Yours was 14.1 inches off at 90 feet!!! (If Pythagorus is to be believed). That extrapolates to 47 MOA off.

    really odd.

    I think they actually mention that in the owners manual too (the what?!??).

    When I read this I immediately thought of one of my recent shooters here at the farm, who came to me for "lessons". He like'd highpower'd calibers, Weatherby MK5s 300s, 7mm Mags, light-weight Browning SA 300 & 270 WSMs etc.. (no muzzle brake) but couldn't hit a bull in the butt with a bass fiddle at 100 much less 200 yards.

    While part of his problem; he was what I call "recoil" sensitive, meaning after the first shot he was toast as far as accuracy went - his real problem was he didn't understand the fundamentals of using a scope.

    When you mount your rifle, unlike your woman, it's best to do "it" the same evertime.......and by that statement I mean your eye needs to be "squared up" and positioned behind the scope perfectly, with a totally "clear", no shadows anywhere type of precision. (it's another reason to chose quality scopes, I speak old Leupold VX-IIIs grade and up myself in this regard, as it was what I learn'd and was taught on - why because they, as well as other brands have "POP" when your eye hits the sweet-spot, again, but in this instance, just like your woman).

    When one has a scope that exhibits this "sweet-spot" that is where your eye should be before ever giving thought to placing your finger into the trigger guard on any rifle.

    Bow-shooter's know that if their draw-point ain't consistent their accuracy won't be - and the same principle is present when using a scoped rifle. (my own personal preference is I like to "bear-down" on my stock and ALL my scopes are all set so that this modicum of "pressure" forward on the stock, allows me to "see" the pop mention'd above - your preference may vary and I prefer rifle owners to set their own scopes where they fit them not me, but do use my rifles sometimes to illustrate to others what I mean by a "clear" scope and pop)

    Once my student and friend learned this fact, he found that his "first" shot always went within a .25-.5" of his aim point @ 200 yards and more importantly, he learn'd to trust both the rifle/scope combination, no matter the caliber, as well as his ability to make those one shot kills he so desperately wanted on his last trip to S. Africa (and did well as 4 outta 5 ain't bad - although - in S. Africa there's no such philosophy as a 'one-shot' kill, for no matter how perfect the shot ya make you always got guides and trackers behind and around ya holler'n, "shoot-it-again" before the smoke has even cleared.....)

    yep

    it's like the Browning SA22 takedown I've been shooting since I was 11.
    Knurled knob snugs barrel to receiver.
    Like the takedown Ruger, the rear sight in on the barrel with the front sight.

    Loosening the knurl does little to nothing to accuracy if you line up the iron sights.

    47 MOA off??

    something else was happening we don't know about

    Thanks for the information y'all. Just picked up a T/D and will keep this in mind.

    With all that he says about his eyesight and the need for optics, how could you miss the fact that the OP has a scope mounted to his rifle? Lol

    Yep, on the TD the scope mounts to the receiver, so a wobbly obvious loose barrel nut would easily throw accuracy into the "minute of barn" range.

    The scope is mounted on the receiver, not the barrel. At my age, I can't see both factory sights at the same time I thought the bbl was snugly affixed by hand tightening, but no.

    And, yes, it was WAY off.

    Worse, it is one of those new "auto re-center" scopes. I wish things would stay simple, but no.

    Ahhhhh.
    Thanks.

    How could I miss it??
    Merely by posting to discussion boards while also doing something of importance, eh?

    Actually he did not actually say he had an optical scope mounted to the receiver.
    He merely said at his age he must have an optic.
    His post, immediately above, confirms you are correct.
    My bad for multi-tasking while on the job! Bad example for my employees.

    You are right, though.
    Optic on receiver, wobbly barrel. 47 Pythagorean MsOA off.
    Ya, ya. You are correct.

    Or is it MOAs?
