03-A3 extractor with a hole

[Merc]

Can anyone tell me the purpose of the hole that's drilled near the top of an unmarked (Smith Corona?) extractor on my Remington 03-A3? I took the old boy to the range today and found that the cartridge case rim sticks 1/2 way between the extractor and the bolt head preventing the cartridge from being inserted into the chamber from the magazine. In the past, I've always loaded cartridges directly into the chamber and never noticed this problem. There are lots of replacement extractors everywhere including some NOS ones with the R stamped on the underside, but none with a hole.

Sure it's not a 1903 (instead of 03A3) extractor?

Not sure. The gun was a mixture of parts so anything is possible. Were the original Remington 03-A3 extractors drilled? I assumed it was a Smith Corona extractor since there was nothing stamped on the underside.

A picture would help, but sounds like a Springfield or Rock Island extractor. The "hole" is a gas escape hole.

Like Rick said, that isn't an 03A3 extractor. Try a new one-they're inexpensive. Unlike the Remington 700 the Remington 03a3 is not a push feed system so tolerances are a bit more critical.

Thanks guys. I ordered an extractor from eBay with an R stamped on the underside so I'll know that it was made for the Remington 03-A3. It doesn't have the hole.

I took the R 03-A3 and the W M1917 to the range yesterday. The weather was mild for our area with little wind so the shooting was great.

The NOS "R" stamped extractor showed up today and the hook was slightly different from the extractor that wasn't working. The non-working unit must have been made for a M1903. I installed the new extractor on the bolt and it worked well. Since it was blued, I sent it out to get Parkerized so it will match the rest of the rifle. With the R stamp, there can be no doubt that it's the correct extractor for a Remington 03-A3 and it doesn't have a gas hole.

The hole in the extractor lined up with a hole in the 1903 design that allowed gas from a case failure to safely vent away from the shooter. It was not the best method. Later a larger "Hatcher hole" was added/drilled in the left side of the receiver ring corresponding to a larger hole drilled into the bolt to allow gas a more direct safe route for venting. AFAIK, the extractor on as manufactured 03-A3's did not have a hole as it was not needed since venting would have been via the Hatcher hole.

Tolerances in manufacturer can taken together sometimes cause function problems. Installing a new 03-A3 extractor was your simplest and best way to resolve the issues you were having. I have done it a time or two myself with 03-A3 rifles. Sincerely. bruce.

Thanks for the explanation. The best parts are the original parts.

Curious.......You didn't by chance find a "W" or an "E" on that extractor, did you?.......Extractors for M1903 and M1917 rifles are almost identical, bur are not interchangeable. The ever-so-slightly longer M1917 extractors have a gas escape hole like the 03s too. You did say it was an assembly of assorted parts....My $.02

I looked with an eye loupe and didn't see a manufacturer's mark anywhere on the extractor with the hole. The NOS replacement extractor has a R stamped on the inside surface. The hooks look fairly close when you lay both extractors side-by-side, but there must be just enough of a difference to prevent the extractor with a hole from working properly with the 1941 Bonnie Forge bolt.

That's interesting. I'll get back to you with a photo of my drilled extractor in a few weeks when we return from a FL vacation. Yours is definitely made by Remington.

You have an early Remington M1903 extractor - unless you have a Remington M1917 extractor.

I had a the wrong bolt and traded for a Remington A3 bolt body.. I'm surprised the guy didn't trade me the right extractor too.
