My new Short rifle Rossi 92's magzine tube simply does not want to stay put with the recoil and magazine full of cartridges. Think I might need to drill the hole in the end of the barrel deeper for the magazine tube plug screw to seat deeper.

I had the exact same problem with my original Model 92 Winchester. I showed it to a local gunsmith and he immediately started thumbing through a Brownells catalog until he found a set screw with a longer tip. That fixed the problem very nicely.

I would be very cautious about drilling the hole in the bottom of your barrel any deeper...got just a little too far and you're got a "ported" barrel. :)

Have you tried a good thread sealant like LocTite? Are you referring to the magazine tube plug screw backing out under recoil? That doesn't involve drilling into the barrel does it?

The magazine tube on my rifle is retained by a magazine tube ring which is dovetailed into the barrel near the muzzle. The magazine tube is held in the ring by a cross pin. At the end of the magazine tube is a plug which is retained by a screw that passes through a hole in the tube and threads into the plug. Same with your short rifle?

No, the screw isn't backing out, but just from looks, the hole in the barrel is hardly deep enough. You can hardly call it a hole. And there's plenty of Meat in the octagon barrel to go deeper without worrying about porting the barrel. And with the recoil, it's jumping the pin in the magazine tube ring.

From the picture on the Rossi site, it appears the magazine tube plug retaining screw goes completely through both the tube and plug and bears against the bottom of the barrel. Right? If so, and the magazine tube is jumping the magazine tube ring a fix, as you say, might just entail a slightly longer retaining screw with a shallow hole bored into the bottom of the barrel for it to lock into.

That's a little different setup than on my rifle. On mine, the magazine plug retaining screw only goes through the magazine tube and into the plug. I had the same problem with the tube jumping the ring. I replaced the ring and the retaining pin, notched the tube a little deeper with a Swiss file and that fixed the problem. BTW, my rifle was built by Armi San Marco.

Before trying to fix this yourself, why not contact Rossi and see if they will take care of it? You're probably still under warranty. Might be the best approach as they built these rifles so are very aware of fixing these problems. Haven't seen any other similar complaints posted here so Rossi must be doing something right.

Best wishes on getting this fixed.

I'd just as soon fix the problem myself than go thru the hassles of dealing, shipping and whatnot in getting them to fix it. I'd rather do a few minutes of tinkering than have the gun out of hand for two weeks or more. Just was wondering if anyone else was haiving this problem too. A larger pin thru the mag ring probably wouldn't hurt either.

Well now in addition to the magazine tube jumping on my short rifle, my Stainless 92 full rifle's doing it too. This is with my heavy bullet loads driven with 296. It wasn't a problem with my "target" loads (240 gr @ 1000 fps) My heavies for the 92's are 290 and 350 grain FNGC on top of 21 and 19 grains respectively in R-P 44 spl cases. Super accurate though, if I can get the mag tubes to stay put.

Me, too!

My round barrel stainless Rossi 92 .44 mag is having the same problem as described, above.

I silver soldered a stainless ring I turned on the lathe to slip fit the tube, but the solder let go. I'm going to MIG weld the ring in place, right behind the barrel band, turn it to clean it up, and I expect that will fix it. If not, I'll weld a small bead on top of the tube, and notch it for the cross screw.

It's a marginal design, at best. I don't see how the one little magazine tube plug screw could be expected to hold it all together.

In addition to all of this fun, the gun shoots about 6 inches high at 25 yards, and a little higher at 50 yards. It's as if the rear sight isn't cut deep enough. I guess I'll get to clamp it on the mill table, too.

I worked on both mine last weekend, I noticed that the ID of the magazine tube ring is noticeably larger than the magazine tube, this may be the reason why the magazine tube plug screw is failing to keep the tube in place under recoil. The pin thru the ring is also supposed to keep the tube in place under recoil, but with the freeplay, the tube jumps the pin. I wrapped the tube with electricians tape both at the receiver end and at the magazine tube ring. I'm hoping this will help fix the problem. When I get a chance to work on em again I'm going to mic both parts to see what the dimensional differences are and help find a better fix. I ordered a replacement tube plug and screw from Dixie Gun Works hoping the screw was longer, but it's shorter than the Rossi screw. Thread pitch is different too. After reassembly with the elec tape, there's no more freeplay between the tube and ring.. I'll have to wait for a chance to test fire both to see if it helps.

I wonder whether the tape will provide enough friction, given that the existing systems weren't adequate to keep it in place. My .44, with full magnum loads, kicks like a mule, so it's hardly surprising that the meager attempts to secure it are failing.

I'm going to MIG weld mine, and I'll post the results after firing a few rounds. If it works out, it looks like I might have me a little cottage industry going!

Mine suffered from the same problem. I pinned the mag tube to the tube hanger with a roll pin. It only cost me 2 rounds capacity.

It may not work, but I figure it was worth a try. If it does help, bushing the magazine tube ring would be my next step , rather than welding on the magazine tube. I can weld, but not that good.:D

Have you had a chance to fire a few rounds with the tape in place? I received my stainless MIG wire from Enco, yesterday, so I'm going to try to weld it, this weekend, and try it out. I'm not going to invest in tri-mix, so I'll use plenty of anti-spatter, and I'm prepared to chuck it in the lathe to clean it up, afterwards.

If welding doesn't work, I'll pin it, like txhunter77. I can give up a couple of rounds a lot more readily than I can tolerate the magazine tube sliding around.

I won't have a chance to go shoot for at least another week or two. I'll let you know if it worked.
Yeah, let me know. I'm interested in finding a solution to this problem. I have some brass shim stock that I could use inside the retaining ring, if it seems to work.

I welded the ring onto the mag tube, turned it down, cleaned up the inside with a boring bar, and shot 5 full load .44 magnum rounds. The mag tube moved about .030" forward, and cocked the barrel/mag tube retaining ring, slightly. I think it will work, but I'm not satisfied. I don't want it to move, at all.

I'm considering welding a lug at the rear end of the mag tube, and using cap screws threaded into the receiver to hold it at the other end. I'd weld it to the reciever, but I'm not sure I could clean up the inside of the tube if there were any bulges from welding that might interfere with smooth feeding of ammo.

It seems to be a very poor design. How are the Marlin and Winchester mag tubes secured?

The Winchester tubes are secured the same way, but they don't have the freeplay between the tube and ring. I have an older Rossi blued 44 rifle that I bought back in 06 that doesn't have this problem. I think the Winchester also uses a larger pin thru the ring (I need to check that aspect when I can) My 86 Browning rifle is likewise secured as such and other than having the forearm tip tenon shoot loose when new(sent it back to Browning and they fixed it for free), the magazine tube has never moved even after it's had at least 4000 rounds fired thru it. I think that it's the slop in the fit allows the tube to jump the ring pin and the magazine tube plug screw and once that's taken out, it shouldn't shoot loose at all.

I took a very close look at my forward ring, and the screw is clearly drilled off-center towards the barrel. I can't even put it on in the wrong orientation. I don't know if this is intentional, but it almost guarantees that the notch in the mag tube isn't engaging the cross screw.

Maybe I need to make a new forward ring that fits, properly. I could use brass, or stainless, and I'm sure I can make it more accurately than the one that's on there, now.

You know, I'd send it back, but I don't have much confidence that they will fix it, correctly.

I'll try some shim stock, and see if that helps.

I'd send mine back too, if it weren't such a PITA. Besides, I don't mind tinkering with stuff. I'm going to shoot mine this weekend, I'll keep you posted on the results.
