Can you explain need?
The Remington extractor is designed for a specific bolt face. If you open up the bolt face for a different head size, you may not be able to make a Remington extractor work.
Vern called it. Once I opened up the original Remington 223 bolt face the original Remington extractor could no longer be used. The popular alternative was to mill a slot in the Remington bolt and install the Sako extractor. The Remington short action .223 bolt face comes in right around 0.384" and needs opened up to accommodate the 6mm PPC (actually we were fire forming Lapua 220 Russian cases) and needed a bolt face diameter around 0.448" allowing 0.008" over. Thus a "need" for a different extractor. The gentlemen teaching me at the time was a Mr. James Messer and it was on his recommendation I used the Sako extractor. This proved to work out just fine.
Instructor at the school at benning?

i heard range 66e got upgraded after they "changed" the course critria back in 07. havent been to jfk in awhile.
66E is automated downrange now, and each lane is controlled at each firing line by the instructor for that lane. That means that in theory each lane can be firing a different table at the same time, and no one needs to "work the pits" downrange- instead they are training on other tasks.
I had a similar experience building a 6mm PPC on a Rem 700 action except my original rifle was a .308 Win. Talking to many benchresters, I learned the accepted practice was to install a Sako extractor & silver-solder a reducing ring inside the bolt face. It seems to be a common procedure & a number benchrest gunsmiths offered to do it for about $150 by just sending them the bolt. On one shooter's recommendation, I decided to use the bolt "as-is". Extraction is about 90% reliable. If case doesn't extract, closing & re-opening a second time gets the case. That's acceptable for a target rifle. I did a lot of searching & was surprised that no one makes an after market, over sized Rem 700 extractor ring with ejector cut-out considering the popularity of that action for rifle building.
Yeah, the .308 guns and a host of other short actions like the 308 have a 0.473 bolt face diameter. Some guys like to silver solder a reducing ring and run with the existing extractor. Some like you have really good success while others have lesser success. Since I started with the 223 bolt face and did my own work I wasn't paying a gunsmith but got to do the work under the eye of a very good gunsmith. I have given some thought to calling someone like PTG who turns out custom bolts and asking them to make me a bolt if I send them the action. Then too, I have not shot that rifle in a good many years.
