The large majority of T1x owners will not have to do these modifications to make your T1x function any better. If it's working good don't mess with it. Mine wasn't working good after I installed the IBI barrel with Win 52D chamber. Everything functioned fine with the 1st IBI barrel and the factory barrel. The 52D chamber is so tight the bullet has to align near perfect to successfully enter the chamber. I worked with what I am about to show for a few days. I did quite a bit of experimenting to try and eliminate my jamming/feeding issues. Extraction and ejection has never been an issue.
The pitfall to the T1x design is the way the ejector wire is designed to work. Its purpose is to eject but it also rides on the bullet making contact with it. This pushes the top round to the right as the round leaves the magazine and does not allow the rim of the case to slide up as far as it can between the bolt face and extractor. This also keeps the tip of the bullet low and it hits the bottom of the chamber when trying to enter it. Since the IBI barrel chamber is so tight, the bullet doesn't have as much wiggle room as with other chambers. **Keep in mind, the Win 52D chamber was designed for a single shot rifle, not a magazine fed one.** So let's just fast forward a bit to the outcome.
I finally realized I needed to get the ejector wire away from the bullet BEFORE the bolt made contact with the rim. To do this I made a do or die bend in the ejector wire. This allowed the bolt to move the ejector wire to the left and out of the way as the round was being stripped from the magazine. It took a couple of tries before I got it just right. So, finally I was feeding a round into the chamber almost perfect. To my surprise it was ejecting the live rounds too. But from past history I knew that just because a live round can be ejected, doesn't mean a fired round will be ejected. So next step was to shoot some. I ended up shooting 40 rounds with CCI SV and Aguila, to of my worst feeding ammo. To my surprise everything worked perfect without one failure.
While I was back inside I noticed that sometimes if the top rear of the mag tilted down very far the bolt could ride over top of the rim and push it out of the magazine making it stand up, bullet first. I have read where this has happened to others but this was the first time I experienced it. So I studied the design and concluded that I could put a shim on top of the mag ejector lever and possibly make the mag fit tighter and higher up to keep the bolt from overriding the rim. After that everything was fixed. I took it a step further by adding two layers of duct tape to the bottom of the mag and one layer to the top as shown in the photos. If you do it any other way the mag will not drop free. All this combined made the magazines fit much better, eliminating the stovepipe jam and making overall feeding appear to be better.
Below are the photos of what I did with commentary as needed.
Here is the final shape of the ejector wire. I removed the wire to make this bend.
The following are a series of photos showing how the bolt pushes the ejector out of the way to allow the bullet to freely move up and out of the magazine. The bolt needs to make contact on the ejector right before or at least at the same time as the bolt hits the rim. Some of these photos may be the same or show the same thing but just with the flash on.
