Stud Extractor

Post by 123rover50 » Tue Oct 29, 2019 2:41 pm

Does anyone know why the stud extractor was scrapped?
Looks a functional simple thing in line with its rolling block action.
Was thinking of making one instead of having to mill the barrel for the sliding one.

I think it was because the stud extractor at times would rip through the thin rim of the early copper cartridge cases leaving the cases stuck in the chamber. I don’t think it would be a problem with brass cartridge cases

That could be right.
Looking at my 45-70 with the concave breech block it might work with a stud extractor.
This 40 cal rim is too far away from it to work. It might work if I had a flat breech block instead of the concave one.
I will just mill the slot for the bar extractor anyway.

Both of the 1867 Navy carbine and the Navy Cadet rifle had concave breech blocks with the stud extractor. I think i have photos of them on my computer, if not i will take some photos of the breech block this weekend for you to see.

Have a Good Day,

Here is a photo showing the stud extractor on the breech block on a 1867 Navy carbine.

Good pic . thanks.

I wonder if its because those cases are a big diameter, hence the concave BB.
Milling a slot in the barrel for a sliding extractor might weaken it by getting to close to the wall.
The case head is close to the concave so makes the stud extractor easy to fit.
As cases got smaller , the heads were further from the BB so making the stud inefficient as an extractor.
Cases were smaller so more meat in the barrel to cut the slot for the extractor.
No need for a concave any more so BB,s became flat as easier to machine.
I have not seen any flat breech blocks with a stud extractor.

Since the largest case and rim size offered in Rolling Blocks had a sliding extractor, I doubt a sliding extractor would weaken the barrel. Every Rolling Block I own is a sliding extractor, and never had an issue with them.
I've heard of people getting cases stuck and hammering on the breech block which broke one, but I've never been that brutal to mine.

The Egyptian Rolling Block was made with both and had a case/rim size the same as the 50/70.
