Spring/Piston My TX200 Has Done it Again. . . Broke it's Scope Stop Pin

[Hoppalong Doc]

As much as I love my TX200, It broke again this afternoon. Well, not the rifle itself exactly, but the scope stop pin sheared off. I use Sportsmatch scope rings with the pre-installed stop pin (from AoA). This is the 2nd time in the 6 years I've been shooting my TX200 that its severed this pin. As I always do, prior to shooting, I tightened all the stock, trigger and scope fasteners. This time the scope moved back nearly half an inch before I caught it. This past winter I installed a Vortek PG4 full-power tune. The firing cycle is smooth and quiet, as expected. I have two other springers, a HW97K and a HW50S. What am I doing wrong? Should I be using another brand of scope rings? All my scopes are quality Hawke scopes, so I 'm not worried about them as they have lifetime warranties. So help here, friends . . . Orv.

You are not doing anything wrong. It's just physics. You can add weight to the rifle somehow or use a lighter scope. Perhaps you can add another scope stop (without a pin) behind the front ring. Something like this?

I have used those scope stops before on other springers, but my TX I have never had an issue. I am only shooting 11 FPE though.

This is what I used on my Diana 48. It never moved at all.

What's the torque on the scope rings? I torque mine to 30 in lbs. This is surprising since the TX is a smooth shooting gun.

Hey Doc, my question would be; what are you replacing those broken stop pins with? Maybe they are a softer (or hardened) metal and can't handle the stresses of the repeated recoil from a springer?
I am running the same rings on my TX also with a Hawke scope without issue, although I doubt it gets shot as much as yours? This winter it will be 3 years old...time flies, but no broken scope ring stop pins yet.
What i would do if it becomes a constant problem is to drill the ring base out and install the next size up pin and/or source the pins from somewhere else?

First of all Dan, I'm using the pins included with my Sportsmatch Rings. These are a premium brand as far as I know. They are high rings because the Hawke scope I'm using is 30mm and relatively long. I could go into my ritual of tightening everything down before shooting but I'll refrain in fear of boring you all to death. Anyway, I spent quite a good while on the phone with the tech from AoA before narrowing the likelihood of my problem being that I'm not pounding the drop pin far enough into the top of the receiver rail. I've also noticed that the hole in the current ring seems to have morphed from round to slightly oval. To answer your question Dan, the drop pins supplied by Sportsmatch are a rolled piece of steel, giving the pin it's strength. The new rings should be here on Monday, so we shall see. It got to late to hit the range this afternoon so I gave the rifle a good going over with Renaissance Wax and a few drops of Pelgun Oil applied appropriately. My TX200 has given me fits over these 6 plus years of service, but I'm truly convinced that its now operating at it's potential. Now if I can operate at mine as well. For these next few days my HW97K will just have to suffice. Aww, poor me. Orv.

Tony: my TX200, .22 cal., with it's Vortek PG4 tune hits in the area of 15 fpe., varied a bit by which pellet is being shot at the time over the chronograph. By the way, I'd sure enjoy watching you and your favorite blonde competiting one day over there in the desert. Might even try getting off a few shots myself. Orv.

Thanks for your reply. Unfortunately, my Hawke scope work as its a 30mm tube. I have a one piece scope mount that I've tried, but it wasn't able to fit. Thanks again, Orv.

Use a tiny amount of grinding compound in the scope grooves of the receiver .. Then mount you scope rings on top of the compound..

Tell me how this works, please, Orv.
