The Tx200 arrived safely and is scoped up. I opted for the walnut stock. Some users of the TX200 may not be aware that unlike the beech stocks, the walnut stock needs to be conditioned in some way at least once per year to prevent shrinkage etc. You can us an oil like Danish oil, though I prefer to use bees wax, which I normally apply every month or so. Oiling can change the colour of the stock, so a sensible precaution is to test the oil on a small part to see what the effect is.
Although it is early days, my TX has a preference for Air Arms Diablo and Crosman Premier (heavy) pellets. I have opted to go with the Crosman's at this stage, but this could change as after a thousand or so pellets have been shot.
