Is my cooey 75 barrel bent?

[Jessegreenwood]

I have a cooey 75, and the bottom is strait, even where the barrel tapers. So the top pitches down, and from the outside looking down the side, it looks like a pretty good bend down.

It looks strait on top, no bend to the side, and looking down the bore, it looks strait as can be.

Do they taper these barrels like that, like the bore isn’t centred before they taper, but they taper centred on the bore, not the outside round? Or did somebody fall on this thing?

Also, is a bead of silver solder on the front site standard? Thought it was a nice touch, but didn’t see it till I cleaned the gun up with some steel wool.

Post a picture if you want an answer.

So far as I know, a barrel is checked for straight by looking down the bore - that is the part that "counts" - would be nice if that was always dead centre within the barrel, but I have had several examples that are noticeably not so. I think the Clyde Baker gunsmith book - so 1920's (?) or so describes the procedure - is about having a cord or string hanging in front of a diffused light, backlit window, so that a shadow line is cast down the bore - rotate the bore looking for "kinks" in that shadow. Somewhere's else I have pictures of that process being done, and the bores being straightened, in a Remington plant and in the Anschutz factory. A poster on CGN had previously mentioned that Cooey factory would have .22 in a jig / vice and bend barrel to get sights hitting where they wanted.

Even with a straight bore it may not follow the center of barrel. Staight bore= all good. Solder on a Cooey ft. sight is common.

Is my cooey 75 barrel bent?

Are you able to sight it in? When you shoot it, where is the point of impact in relation to where you are aiming?

It shoots strait. Very strait as far as I can tell. Have considered bringing a bench clamping vice to the range to find out how accurate the gun its self is.
I...am not that accurate. I bought the cooey so I could practice cheaply, to become an ok shot before practicing with my lee enfeild at 2 bucks a pop. My goal is to be deer hunting accurate at 100 yards by the fall.
But quick. That is why I like the cooey, similar length and sight picture to my no1mk3* so I can practice consistent shouldering, sight picture, and shooting as soon as the sight gets on target.
So it will be a while befor I can tell if the gun is 1 moa or 5.
But when you have that moment when it goes pop and the sight picture freezes in your head, yeah, it seems to put the bullet right on the spot, as far as my eyes can tell.

OP - I do not remember the resource, but I had read that barrels, within "reason", do not actually have to be perfectly "straight" to be accurate - it is in my mind that only last bullet length or so of the bore actually determines direction and accuracy of the round - hence dings to muzzle are usually a nasty thing. End test for you is as mentioned above - does it shoot well and hit what you are aiming at? "shoot well" is about mechanical function - "hit what you are aiming at" is a function of sights pointed to where the bullet goes, and whether the shooter can tell or not. "Accurate" is whether all the bullets go to same place - what is demonstrated in a "vise" or a "rail" may not apply to a shouldered rifle - all kinds of different vibrations and "shakes" going on as the bullet heads on down that bore...

Keep in mind that the kill zone on a broad side white tail deer is sort of 8" to 10" diameter - roughly (heart / lung area). Poke a bullet through there and the deer dies. Do not have to hit a specific hair to kill a deer. Do not have to be able to hit it's eye at 300 paces. I had mentioned previously, perhaps to get my son started - I bought a bunch of paper 8" or 10" paper plates. Stapled them on lathes. Drove them into ground at random ranges. Pick one. Take one shot - use same position as if you were hunting deer. Will not be shooting strings or groups when hunting - will be depending on that one cold barrel shot - hit or miss. If get a hole anywhere in paper plate, you got your deer. Keep working to further and further ones. At some point you miss. That one was too far for you and your gear. So learn to hunt within your limitations, whatever that might be.

I once had a Cooey 75 that shot really well, but a huge rifle for a single-shot .22. lol When you looked at the barrel's crown, it appeared as though the bore wasn't centered in the barrel itself. (not "concentric?") Shot great though!
