Hello, I'm new to this forum but would like to say this is the best information I've found and you guys rock! I have a Big Cat 1200 in .177. It's all stock except for the GRT-III trigger I installed and a Centerpoint 16x40 scope. I have a question regarding spring fatigue. I accidentally left my gun loaded over night approx. 3 times for about 10 hours. I am curious how long it takes to ruin a spring or cause spring fatigue? I'm worried, did I weaken the spring? I'm very curious if this has decreased the velocity output of my gun? If anyone is knowledgable on this subject I'd love to hear some advice. Thanks guys.
