bolt face question

[gatewood]

I just had a rem 700 with 223 bolt face opened up to a 308 and a sako style extractor put in to replace the rem one. my question is can i do the same to take a 308 bolt face and open it up to a mag. face or will there be to much of the old extractor grove left to work?

Opening up to .545 for a Mag boltface will not clean up the counterbore. That requires opening to .625 and installing a
sleeve or ring to get you down to .545. It can be epoxied in or soft soldered,which I am sceptical of) before making the cut for the Sako extractor.

What about taking the whole nose off and make it like a Savage bolt face? Shorten the firing pin and there ya go.

SRM i have never seen or heard of this. you have my curiosity up please enlighten me farther on this.

You will be able to buy a new magnum bolt for less than the cost of paying someone to convert a Remington bolt to accept a Savage bolt head.

but it would be part savage so it would be that much better.

I`ve never liked those noses,the extracter, and its more work when doin a chamber.I dont know if there is enough material between the lugs for a new bolt face,need to look.But then use a savage or sako style extracter. just thinkin

Why not just buy a bolt from Dave Kiff?

already got a pt&g bolt on the way! but would still like the details of changing the configuration of a rem bolt.

bolt question: my ghog hunting buddy has a factory savage .243 that has a very slight dished- in surface to it's bolt face. fired cases have primers slightly buldged around the firing pin indention but no leakage of gases. his other savages have flat bolt faces. he's contacting savage but would like info from shooters. thanks.

if i can see you, i can touch you. BANG!

Most Savage bolt faces are 'dished' to some extent from the polishing process, the larger ones being the worst. You may also find a slight chamfer on the edge of the firing pin hole. A simple facing cut cleans them up.

You might also see the firing pin tip is ground on a taper allowing a gap between the pin hole and pin tip at about .020' protrusion, roughly the amount a primer stops the firing pin forward travel. Reshaping the tip to about a .020' radius allows the full diameter of the tip to remain in the pin hole and eliminate cratering provided they're not because hot loads.
