Re: The 425 Express - an overlooked caliber - 2 rifles
Quote: "... You have a great action there with the Mark X, mine was a bit stiff initially, slowly coming good.
I use RED jeweler's rouge smeared all over the bolt and action and I work the bolt a few hundred times while watching TV. Then I thoroughly clean everything with brake cleaner and apply lithium grease. The results is a slippery smooth action.
