My Cooey 600 does not have a grooved receiver and the suggested Weaver side mount system puts the scope off to the side of the barrel. I will have a gunsmith D&T the receiver for mounts. Have any of you out there done this, and what mounts did you use. I plan on mounting a 3-9x40 Bushnell on the rifle. Thank you for any and all information.
What top mounts for a Cooey 600

I did that on a Cooey 39 - same size receiver, I think? Used a Weaver 92A "rail" - required creating my own "hole" in the rail for one screw. Used hacksaw and file to saw out a rectangular notch to match the action opening. The 92A seemed have very close radius underneath to match the Cooey receiver. Typically you are not going to be too happy with a center fire scope - parallax will be set much too far for rimfire ranges - some people think they are fine - maybe will work for you. By the way, same story on my Cooey repeater, except mine is the Cooey 60 - someone drilled and tapped for a side mount base - hole spacing fit perfect to the Weaver base unit, but the apparatus sets my scope noticeably offset from centreline of the barrel / action. I got it "straighter" by installing a strip shim behind the base, above the screws, but does not look "correct"... When I get back to it, I plan to re-set it and drill and tap new holes so it sits "straight"

The side scope mounts won't offset the scope if the installer is competent. The receiver rail can be installed at any angle to assure that the centerline of the detachable bracket is directly over the centerline of the bore.

I remember your earlier thread on this - the actual performance of a rifle scope with a slight offset is just fine, so it is just the aesthetics that bother you this much?
Yes, I had an earlier thread on this. This past week I took the rifle completely apart, cold blued the barrel and receiver, stripped and sanded the stock, and applied truoil walnut stain and 7 coats of truoil. Tomorrow it will be ready to put back together. I do not like the scope offset from the barrel centre, partly because of aesthetics, and I don't feel comfortable with my head that far off centre of the rifle. I installed the side mount, as well the local gunsmith did( who does work for people all across Canada, and knows his trade VERY well) and he said that the mount was designed that way and could not have the scope centred without a lot of machine work. I decided to have the receiver D&T late this afternoon. I called him to see what mounts I needed, but he was away, so I thought I would ask on this site.

Like Potashminer, I've used Weaver one piece bases and drilled the barrel, installing the base backwards over the action.
My 600 must have been the later design with the grooved receiver.
Somewhere I heard that it won't eject properly with the scope on top hence the side mount offset.
I can testify it does eject the same with or without a scope directly on top.

Good to hear about no ejection issues on your Cooey - on mine, as well I think for the OP, the issue is that the scope is offset to the right of the barrel - over too far, past Top Dead Center. In 1970's, I had installed a similar, but different angles, Weaver side mount base unit on a Win 94 lever action - that one ejected straight up, so scope had to be significantly off-set to the left, and the scope turned counterclockwise a quarter turn to get the windage turret out of the way. That commotion did not help me - I still was missing white-tails with it, even with that scope...
