No expert either, but with 8 to 10k pellets, that sping had a nice long life. I only got about 2500 each on both the springs in my CFX, before swithcing to the gas ram. My bosses S1K is the same with Superdomes, they drop in with no resistance. But turn the barrel up, and they stay in place, and it shoots them like crazy. If it was me, I wouldn't worry about it. As the man said, if it works, don't fix it :-)! I know, that doesn't apply to airguns and airgunners, but whatever....
