Unfortunately the size extractor you're looking for is very difficult to find. The 222 and the mag extractors are available if you look hard enough.
At one time Remington modified the 722 and the 721 bolts so that the 700 extractors worked. I'm not sure if they still do that -- it was expensive.
There are people that think Sako extractors are better. I believe they are somewhere between fools and idiots, perhaps morons. But having a gunsmith convert it to a Sako extractor may be your best option.
