Last summer I reported my frustration with the gritty feel and inconsistent release of the trigger in my particular TX200HC. Having been assured that this was not normal, I finally got around to tearing it down to see if I could identify the problem. I had previously removed any wobble from the trigger blade by making a thin bushing from shim stock. This had helped a little, but did not completely eliminate grittiness and inconsistency. This time I pulled both sear levers and found that both had some rounding of the sear edges. I honed each sear lever dead sharp using a diamond honing plate and voila, problem solved! The trigger is now light, smooth, crisp, and most importantly consistent.
The next thing that needed upgrading was the scope. I had a Nikon 3-9 EFR on the rifle, but it did not offer enough magnification to see pellet holes at 50 yards. I am somewhat of a fan of Bushnell scopes, so I took a chance and ordered a 4-12 Trophy from Midway. I didn't go higher in magnification because I didn't want to add unnecessary weight to an already heavy rifle, and I wanted to keep the scope behind the loading port if possible. Optically this is a great scope, and I like the side parallax adjustment. My only reservation is that the zero reset adjustment is not easily made. I requires loosening and retightening two very tiny Philips head screws when resetting either windage or elevation. This is not something you would want to do in the field.
I took advantage of a quiet winter morning to zero the new setup. It took a bit of shooting to relearn how to handle this rifle off of my Stoney Point sticks, but I did finally start getting some decent groups at 35 and 50 yards. The last 8 shots at 50 yards were all within the black on the center bull, which is probably about the limit of my shooting ability with a springer. I did install a Vortek kit in this rifle last year, and with these additional upgrades it is now the most accurate conventional springer I have owned.
Good shooting!
