WELCOME to the GTA JT,
Your choice of the CFX is a sound one, it's not an Anschutz, but with the proper shooter, it will do it's part. As PeakChick pointed out, with the proper scope, glass is always an important factor, as I'm sure you know.
I hope to read your thoughts and opinions on the CFX,after you have had a chance to run it through the ropes. The GRT-III trigger modification is a must, as the Gamo rifles have the worst trigger that I have ever used. The GRT-III will correct that problem in 5 minutes, and make your CFX a dream to shoot !
I wish you success in your entry to airguns ! And hope you stop by here often !
As You May Already Know, The G.T.A. Forum is a GREAT PLACE to BE !!!
