Greetings, all!! I have a Snow Wolf M40, and I use it ONLY for target shooting. It came stock with a spring of around M135 strength. It seemed a bit weak, so a few months ago I upgraded it to a (supposedly) M170. [I qualify that statement because it's not unknown here for shops to keep wrappers/packages for a style/size etc of part which they no longer have, and when a customer requests one that they don't have in stock, they just pop another type into the package and sell it as genuine].
So this was a Red Wolf spring, and after about 8-10k shots it seemed to be getting weaker. Since I'm re-building the grip (using epoxy-putty to create finger-grooves) and have the rifle apart, I figured I'd do something about the spring as well. So last night, I tied it to my weight-bench and hung 20kg from the bottom of it. This morning it is about 6" longer! lol
Questions:
1. What is the opinion of 'Red Wolf' springs? What is considered the best (longest-lasting) brand of spring?
2. Is it common for these kinds of springs to lose strength after that many shots? (And no, my arm's not getting stronger..
3. If I reinstall it, will having that extra length compressed into the cylinder cause any damage to the cylinder/bolt-handle joint? (This cylinder is of the 'pinned' type, not just crimped.)
4. I was going to clean off the grease I'd used before and lube the spring and guide-rod with some MOS2 lube, as it seems thinner and less 'sticky' than the (basically) axle-grease I'd had on there. Which would you say is better? I can't find any lithium grease at the stores.
Thanks!!
