Frequently Asked Questions

How should I lubricate the bore of my Winchester Model 70 for storage?

For storage, run an oil-soaked patch through the bore of your Winchester Model 70. This deposits a thin protective layer against rust. If you plan to shoot the rifle within a couple of weeks, you can skip this step unless you are in a damp or salt-water environment.

What parts of the Winchester Model 70 bolt require lubrication before reassembly?

Before reassembling your Winchester Model 70 bolt, lubricate the firing pin spring with a couple of drops of oil. Apply grease to the camming surface on the cocking piece and a drop of oil to the rear of the bolt rod to ensure smooth operation and reduce friction.

Is it important to use a specific type of lubricant for my Winchester Model 70 bolt?

While the video doesn't specify exact lubricant types, it emphasizes using a minimal amount of oil and grease. Too much lubricant can attract fouling. A general firearm lubricant suitable for springs and metal-on-metal contact points is typically recommended.

What is the purpose of lubricating the camming surface on the Winchester Model 70 bolt?

The camming surface on the cocking piece of a Winchester Model 70 bolt is crucial for the firing pin mechanism. Lubricating this surface with grease helps ensure the action cycles smoothly when you lift and operate the bolt handle.
