So I rebuilt much of my TX200 MKIII after about 15,000 to 20,000 rounds. It has been doing great. New spring, compression tube, seals, bearings etc. However I couldn't get a cocking shoe. As it is a major pressure point it seemed like it could wear.
Anyway, today I was shooting at 100-yards and noticed that it had some spring noise and was a bit inconsistent.
At home the chronograph showed it jumping around. It was in the upper 800's at the top end. Lower than it had been with these 8.4s I used to test. The breech seal looked a bit off so I replaced it. I relubed the action while I was at it. Now, in fairness I had been running some relatively tight slugs recently. I would expect those to stress tge breech seals. The heat and humidity can mess with things due to condensation as well.
After tweak, the chronograph showed a jump to low 900's with the 8.4s and an ES of 7fps over 5-8 shots. New seal and lube so it will settle a little yet.
Question 1: How often do you TX200 owners find yourself replacing breech seals.
Question 2: When my cocking rod releases front stop there is about an inch of free play before the slack to cock starts. Is that about where yours is?
Question 3: Pyramid is out of cocking shoes. All other vendors appear to be as well. Anyone have a sourse for a new cocking shoe? My fear is the wear may have left a larger gap at the barrel causing undue stress on the breech seals.
Obviously I can just mass order breech seals, but a bulk source would be great in that case.
