I am a shotgun guy and would never leave a shotgun with it's hammer cocked when in storage! But what about a rifle? I just purchased a nice remington nylon 66 to start my 10 year old grandson shooting. After a good cleaning I need help in how to store it. The fellow I bought it from had it in a gun cabinet for probably 20 years with the hammer cocked, do you think I should have the hammer spring replaced? Thanks for any help. Should I and How? relieve the tension on the spring?
