Interesting side note to the GRT III trigger. A couple of weeks ago, I had a friend stop by with a 10M match rifle. I think it was a CZ PCP. Took that and my rifles out to the shop for a little indoor 10M action. My rifles are a CDT tuned CFX with GRT trigger and a Diana 350. The whole point here is a comparison of the triggers. Those that have read some of my other posts on the 350 know I'm not thrilled with the trigger. But here's where it gets good. I shot the match rifle a few times, and was really impressed. As a general rule, I can barely hit air shooting off hand, but was able to nail a couple of bulls with this thing. Right after the match rifle, I shot my CFX. Despite the very nice match trigger in the CZ, the GRT trigger in my CFX felt at least as good, possibly a hair lighter, and because the blade is wider, it "fit" better. Been meaning to pass this on to Bob, I knew his triggers are good, but I didn't realize how good. Way to go, Mr. Werner!
Dale, I wouldn't worry about the noise from your CFX too much. I have neighbors on both sides, and unless they see me shooting, they don't even know I'm doing it. And that's either rifle. Forget the sound meter, get someone else to shoot the rifle and stand 10 feet away. I think you'll be surprised, I know I was the first time I did the same thing. Also, I tried Ramjets in my CFX, they were consistent according to the Chrony, but low velocity and not especially accurate. Best pellet for the CFX seem to be RWS Superdomes, JSB Exacts with the 4.52mm head diameter, Beeman FTS, Crosman Premier Lights, and Beeman Kodiaks. The first two work best in my rifle, FTS's are okay, anything Crosman sucks, and I don't use Kodiaks because of the weight issue. Probably okay with the Maccarri spring Bob put in my rifle, but Bob thinks 9 gr. should be max for .177 rifles, and that's good enough for me. Besides, I get almost 900 fps and 14.5 fpe from Superdomes. Good luck, and keep us posted.
