Lot of work to add the little material--converting bolt from 308 bf to PPC/Grendel

[carlsbad]

Just completed a couple of bolts for a forum member.



To bush down from the standard BF to a .443 BF I added less than 1 gram of steel. .007 cubic inches.

But the amount of work required makes it not cost effective for common bolts like Remington. Just sell the bolt and buy one with the right boltface. These are a couple of bolts from custom actions and the manufacturer doesn't even make them in the desired bolt face.

On the other end of the scale is bushing the firing pin, which I've been doing a lot of lately, and it is in my opinion one of the most cost effective modifications to a factory bolt.

"I wish I hadn't had that firing pin turned down and the bolt bushed to match." --Nobody Ever.

Now the firing pin bushing job doesn't add any total mass--some mass is moved from the firing pin to the bolt. So I guess I shouldn't be measuring bolt work by the gram.

Ive never seen a 308bf that wouldnt pull a ppc case with a new extractor and thats a very small percentage of the time it even needs that

Those bolts are for a buddy of mine. Nice work.

Does this statement apply to Rem. 700 .308 boltface? I have been told by someone I trust that it will not unless a M16 style extractor is installed. dedogs

How does a 308/ppc bolt face work?

No the factory extractor will not

Its a 308bf that has a long enough extractor tooth to grab a ppc case and enough room around it to swing out when a 308 case is in place

Must be reworked, which is pretty easy for an M-16 extractor and almost impossible for sako or rem OEM extractors. --Jerry

Exactly ^^^

I'm not sure what you're saying Dusty. I've had several and seen many more factory remington extractors on a 308bf pull ppc cases just fine. Not to argue at all. Just stating what I've seen, to the point that I think it's safe top say that unless the extractor is jacked up, a remington will pull a ppc virtually without fail. I've had them to pull some pretty damn tight ppc cases, too. They don't get as much of a bite on the rim but its apparently enough, IME.

Me either. dedogs

Im saying dont bank on a remington extractor working for a ppc. Sure some will but its not a sure bet

Huh?
