I bought a new Winchester SX3 Deer shotgun with the cantilever barrel. I have tried to use several different 1 " QD rings on this gun and they are loose on the cantilever. I used Warne QR, Burris Signature Zee, Leupold QD, and Weaver rings on this gun. I took the gun back to the store ( Gander Mountain) and the gunsmith tried all of my rings and had the same results. The only rings we could get to work were the Millett QD aluminum rings. The store manager bought the gun back and I went to another Gander Mountain and picked up another Winchester SX3 Deer shotgun. Thinking that there was no way this could happen again, I did not check the rings until I got home with the 2nd gun. Well, you guessed it, the rings would not mount tightly to the cantilever on the new barrel either. I called Browning/Winchester and at first they said this situation was not likely, but after talking at great length to their service dept. manager, and telling them it happened on 2 of these guns, they want me to send the barrel back in and check it out. I have mounted many scopes on different types of guns and have never experienced this before. These shotguns are made in Belgium and I wonder if their is some kind of quality issue with these barrels. I know this is a long post and I apologize for that, but I was wondering if anyone else has had this problem with the new Winchester SX3 Deer shotgun with the cantilever barrel? P.S. I have always used Warne QD rings and never had a problem with them. As a matter of fact, when I took the gun back to Gander Mountain, I took the exact Warne QD rings with me. The gunsmith and I tried them on a Browning Gold cantilever, a Remington 11-87 cantilever and a Beretta Extrema 2 cantilever and the Warne rings worked flawlessly. Any help or suggestions will be greatly appreciated.

Do you mean that they are loose in the cross slot, meaning the channel is too wide?  This is common.  When you mount the scope push the rings all the way forward and lock them in, then tighten down the top halves of the scope rings.  This should be plenty tight.  I used the Leupold QRW rings on my Browning Gold Deer Hunter.  Somebody else here can probably better help you diagnose the problem though.

It sounds to me that the rail is machined too narrow. I should like to  think the gunsmith would have pointed out the need to to push the rings forward in the cross-slots if they are too wide, but I guess it could be that too. A few quick measurements with a dial caliper would have told the gunsmith where the problem lies. I'll bet some flunkie machine operator in Belgium made a whole batch of out-of spec rails that slipped past Q.C.

I just got back from Gander Mountain with the barrel and the gunsmith did measure the width of the cantilever mount. He said it is "slightly narrow". I did push the rings forward as suggested. I just was wondering why the Millett rings would tighten down but the others would not? Looks like this gun is going back to Winchester/Browning. My advice for anyone intending o buying one of these shotguns is to check the ring fit before you buy it.

  A real close look at the mounted rings would probably reveal the answer. If it doesn't have something to do with the design of the Millet rings, it would almost certainly boil down to slight differences in allowable manufacturing tolerances from one ring manufacturer to another.

I forgot to mention that the Winchester SX3 cantilever mount is the exact same one that is mounted on the Browning Gold cantilever barrel. They are both made in Belgium according to the service rep I talked to at Browning. The Warne rings that I took to Gander Mountain tightened down perfectly on a Browning Gold, Remington 11-87 and a Beretta Extrema 2 cantilever scope mount.

This is in no way an attempt to hijack a thread, but the question is very similar. I just got a new T/C ICON with the "weaver bases" milled into the receiver. When I used an old set of Weaver rings to check for correct ring height, there was some movement from front to back. All the Weaver bases I have ever used before had a snug fit with Weaver rings. I have a set of Warne rings on order, and if I understand correctly, if I place them in the slot and slide them as far forward as I can, then tighten them down, they should not move.

Although it's probably best to have a snug fit, a little, (or even a lot), of fore and aft movement is not going to be a problem for most applications as long as you push the ring forward as you tighten the clamp screw. This is done, of course, to prevent movement upon firing. The rifle wants to recoil backward, and the scope wants to stay where it is. The effect of these physical forces is for the rifle to slide out from under the scope. If the ring is already in full contact with the lug on the base, it can't go anywhere.

 

 BTW, fordisto, congratulations on the new Icon.  I really like the looks of that one, at least in print , though I have yet to" meet one in person."
