I had my Cooey Model 39 single shot out to the range a bit lately to shoot in between load development strings. Had some good results with Federal bulk packs.
Top group is 1 3/8", bottom is 1 1/4".
Both are 50 yards, iron sights. I think if I make a different target with better sight alignment I could tighten these groups up some.

Thanks, Ganderite! Not sure if I should make a larger inverted triangle target and aim at the base point - or try a slightly larger circle or diamond. I use these diamonds with 1" grid for load development at 100yards - I am still learning what the best targets for iron sights are.
For 100 yards with irons, I use a black rectangle about pocket book size. I staple it on a sheet of paper and re-use it over and over, until it is too shot up. I score the groups on the paper, not on the black/.
The barrel on my 10/22 got leaded up so bad before I noticed that I'm surprised that bullets were actually leaving the thing. Figured something was wrong when I couldn't hit the plates anymore at steel challenge, haha.
Ended up having to knock most of the lead out with a cleaning rod and a hammer (big chunks were coming out, it was crazy), and then chore boy pads took care of most of the rest. I've since only been shooting plated bullets through it (mini mags), and I've never had a problem with leading since.

Those are great groups with the standard tangent type irons on Mod 39 Cooeys. Good shooting.
Some of those old Cooeys shot every bit as well as some of the match rifles of the era they were made.
Considering how they were held in their stocks, with a single bolt, it's almost mind boggling.
Cooeys have most always had a great reputation for accuracy and not being fussy about ammunition. Still, the shooter has to be up to the challenge to shoot them well.
That target shows off your skill as well as the quality of the rifle, IMHO

Ive made up some more targets - going to see if it makes an improvement. We are out of match 22 ammo in my area - disappointong as all I have on hand is bulk Federal 36gr and some CCI 32gr. Was really hoping to try some subsonics and see what the old cooey could really do!

Thanks Bearhunter!
I was actually running a test on the bedding of the old Cooey - I put some strips of rubber band on opposing sides of the single screw and shot groups with it. Without any bedding, the rifle shot better overall - though it seemed to make the CCI 32gr a bit more consistent. I dont think the test was conclusive - and when I get a few more types of ammunition I'd like to run a better test.
I suggest you try standard velocity ammo in the test. The CCI standard velocity is often used for accuracy applications. It wins the accuracy per dollar contest in my rifle.
I bought mine at Canadian Tire.

I will look for that next time I go.
Meanwhile, i tried out a couple new targets: 4.5" circles and 4.5" squares. I held dead on and 6oclock, found that i was slightly more consistent holding dead on the circle, then tied in average groups for 6 oclock holds on circle and squares, last place was dead on hold square.
I also managed to barely squeak a .968" group!
I am having way more fun playing with this old rifle than just about any of my other toys. Sorry to hijack your thread - I should make a new one if I plan on posting results so often.

IMHO, the little Cooey single shot rifles benefit greatly from having their receivers glass bedded and up the fore stock, under the barrel for at least six inches (12cm+) This will definitely almost stop vertical stringing, unless it's your fault. It usually settles down horizontal stringing as well.
Stoning the trigger where it engages the sear area on the bolt, for contact and smoothness helps a lot as well, but it again, depends a lot on how good your trigger control is. We modified some of our old club guns by taking a few coils off the internal spring inside the bolt, that carries the rear of the body forward to hit the striker.
We also took a few coils off the back of the trigger return spring as the shooter has to overcome it's pressure to pull back the trigger and that also increases the pull weight by a pound or so.
When Cooey was manufacturing those lovely little rifles, the would they used wasn't particularly dense. This was done to keep the cost down.
However, they were very careful to keep it straight and DRY. They also kept their inletting quite tight. The combination worked well and they got a reputation for being at least as accurate as much more expensive competitors.
Ganderite is correct about using STANDARD VELOCITY ammunition in that rifle. It's actually what it was designed to shoot well. You and a lot of other people would be amazed at how well rifles they thought were mediocre accuracy wise, shoot when they get away from HIGH VELOCITY OR HYPER VELOCITY offerings. It may be a bit more expensive though.
One other suggestion, make your bullseye smaller, especially when using factory iron sights, or even match, diopter type, after market style sights.
Your eye will take in the size of your target and place the bullet somewhere inside the black, especially with tangent type sights.
Scopes and Diopter type sights are easier to manage and adjust for tight groups. Even with these, many targets have a WHITE center inside of a Black bullseye to help with an aimpoint.

For getting the lead out I use a peened 36" 3/16" 309 or 316 stainless steel rod. Light hammer strikes flares the end and it scrapes the lead out quite easily. It has not affected accuracy of the pistols or rifles at all. Then I use bore cleaners to get the final lead out. The rod just gets the worst of it out. I created it to clean a revolver that leaded really quickly. Like looking down and seeing no lands and groves after 50 rounds. Went with harder lead and solved that issue.
They're like the Marlins of the North.
Growing up in the States, I hadn't heard of Cooey until moving here and getting back into target shooting.
I just love it when regular and inexpensive things are so well made that they can hold their own against specialized
products.
Last thing, going with CCI SV is a great idea as you and others have mentioned. They group a lot better than CCI Blazers in my rifle.
Cheers,
Neil
Conclusion:
Budget Supply got me the Lead Out in only 3 days. (Vancouver to Toronto). Remarkable.
I had already concluded that the scrubbing with the stainless steel brush with Chor Boy got the lead out. Initially I could barely get the rod into the barrel.
All those marks I thought was lumps of lead has been correctly identified as pitting.
I gave the barrel a treatment with the Lead Out, following the instructions. After a 20 minute soak the patch came out read. I don't know if that is lead or steel rust.
Anyway, with the borescope I see no change.
Tomorrow I will re-shoot the Cooey vs Brno. I expect the Brno to do better, now.

Boy, you guys were right about CCI Standard Velocity. I shot two 1.25" groups at 50 yards with irons back to back.
I like happy endings.
Today I took the Brno back to the range and shot it. Now that it is clean, it shoots an excellent group. Better than a Cooey.
Both rifles were shot with the open sights and stnd velocity ammo, at 25 yards.
Brno measured 0.48". Not bad for open sights with my old eyes.
I also shot 15 shorts through the Cooey. Nice and quiet, but a big group.
