I recently had my new Whisper Deluxe tuned by Bob (Charlie Da Tuna). I can't begin to tell you how happy I am with the whole expirience, just great service all the way around.
I've had it back for a few weeks, the first thing that I did was mount a new Leapers 3-9X44 scope on it with a 1 piece Accushot mount. I had issues with the scope creeping with the factory set up, so far the new gear is working perfectly. I already installed the GRT-III trigger, that went in after the very first time that I shot the gun. I also stuffed some foam down in the stock, I think that's helping dampen things down a bit.
So far I've only managed to squeeze about 100 rounds through it due to the cold weather here and I know that it's going to take quite a few more before it's really broke in but man I just can't believe how nice it's shooting already. Now keep in mind that this is my first springer or air rifle aside from my little Daisy when I was a kid, so I don't have anything to really gauge it by. I do know the recoil seems to be about 1/3 of what it used to be and it's much quieter and just all around smoother. There was a little hitch in the cocking mechanism before the tune and now that's like butter. As for the noise, it's makes less noise than the little Crossman C11 CO2 pistol I have.
I'll post some accuracy data later this spring after Ive had a chance to really get aquainted with this unit and figure out what kind of pellets she likes to shoot.
I can't thank you enough Bob, you were a pleasure to deal with.
