Dr. Beretta, I didn't need any Loctite on the barrel pivot screws. They're DAMN tight from the factory.
It also didn't need the Vortek kit, as you may have read elsewhere. It was smooth enough, and I messed with success and they took my money.
What it REALLY needs is a good scope, not too heavy, in the range of 9-16X, and for you to take it apart and Loctite the screw in the front of the trigger group. That little bugger backed itself out on me. It is a wonderful gun, maybe the most fun gun I have to shoot, despite the fact that it is only 7 FPE. It gives about the same power as 10 pumps on the old Crosman 66 PowerMaster with one easy cock. It has that beautifully smooth finish, and even in Beech, it is nice to look at and hold. When you lift it to your shoulder, it feels like a 10/22 and BEGS you to shoot it offhand, instead of punishing you, like most springers do.
Joe old buddy, you're making a mistake by swearing off TX200s. They may never quite compare, accuracy-wise, to a FWB300. What you need for higher power is a Diana 54 or 56TH, with a 12 FPE kit. That'll double your power, compared to the FWB300, but still keep the accuracy.
TX's are GREAT airguns; just not @ 16 FPE. As you know from your trusty FWB300, sometimes, less is more. The TX is another such animal. It was designed by some brilliant Limey for 12 FPE. Then, they decided us Yankees would like it with more power, but still with all steel parts. (because MORE is the American way) Even if it became buzzy and shook our fillings loose. They tried, apologetically, to cater to the guys coming off of the 25 foot-pound Crosmans that don't shoot worth a darn; even working poorly, they're loads better.
