One of the easiest ways to tell if you have the right spring weight and to check for a need to replace is simply to pay attention to where your brass lands during a firing session.
If it's going much more than 6 to 8 feet then the spring is too weak or is worn. If the brass goes less than 3 feet you might have too much spring weight.
Weak or worn recoil springs also account for a large percentage of failures to fully chamber.
