Savage std to mag bolt change

[AceRoth]

I'm switching a Savage 110 from a .473 boltface to a magnum (action was '06, going to 7 rem mag). Obviously, I need a new bolt head. It looks from Savage's online parts diagrams like they have a "standard" firing pin and a different "magnum" one (different part number anyway, not sure what the difference is). Is this something I should change? What other parts do I need to swap?

Also, how do I determine which boltface I need? From browsing midway, it looks like there are several different configurations. Savage's website tells me which one I have now but not what the corresponding magnum part would be.

Thanks.

I believe you need the .562 bolt and make sure if you buy the magnum pin,that you find out whether it is considered the large diameter pin,if it is then you need the large hole crosspin that attachs the bolt head to the bolt body.If you recieve your new pin and it is real sloppy in the new large hole crosspin,use your small hole original crosspin. Just slide each one into the clearance hole in each crosspin and whichever fits the closest to the firing pin size,you use that one.

On top of what Jon said there is a push feed and contolled feed. PTG markets LA, push feed, right bolt-right port bolt heads. I am guessing this is what you need because it's the most popular and you didn't state. Might as well buy a custom ground bolt body from them also. They sure do slick things up!

Firing Pins & Bolt Faces

Over the last several years Savage has incorporated some design changes that need to be addressed in order to acquire the correct parts for your Savage rifle project.
For the last several years, Savage has used a smaller diameter firing pin on their magnum caliber rifles. The reason behind this is the bolt head retaining pin can use a small diameter through hole which makes it stronger. The standard caliber firing pin measures .145" in the area it would pass through the cross pin, the magnum pins are .095" in that area. Because the firing pin diameter is smaller, the cross pin hole is smaller. So is the the diameter of the hole through the bolt head.
Starting in 2001, Savage firing pin diameters were reduced on ALL models. Therefore, when ordering bolt heads it is important to know what diameter firing pin you have to work around.
On the WSM and UltraMag calibers, Savage changed to a controlled round feed bolt head in order to provide reliable feeding from the magazine. This bolt head differs from the rest by having the bottom lip cut away from the bolt face so that the cartridge rim can slide into the extractor instead of snapping over the extractor. Instead of a spring loaded ejector in the bolt face, this bolt head uses a standing ejector located at the rear of the receiver that pops up through a slot on the bottom left side of the bolt head to tip the case out. This is the only way to get the larger cases to feed from a magazine.
