I found the following about Savage bolts on the web (so take it with a grain of salt): The Savage Arms' bolt assembly incorporates a floating bolt head to assure full bearing on both locking lugs. To achieve this, a bolt head retaining pin is used as a "pivot" point. The firing pin passes through a hole in the retaining pin and is ultimately guided/supported by the bolt head. To increase the cross-sectional mass of the bolt head retaining pin in their magnum assemblies, the diameter of the firing pin hole through the pin was reduced."
I don't know how my Savage got the lugs it did then. I thought I would check them for engagement and coated them with Dykem. There was about 25% engagement on one and 40% on the other. So much for full bearing. That being said the rifle would shoot .35" five shot groups from a pencil thin barrel. It was a 22-250 and my cousin has it 15 years later. He shoots 2-3 deer a week with it year in and year out. Did have a funny trigger though. It was LIGHT.
