I'm in the middle of trying to put together my first custom rifle, it will be a very high pressure chambering and a field gun used for hunting in several terrains and temperatures. This has me thinking about extractors. What is the strongest (safest) extractor to use in a high pressure chambering? And is it also the most reliable under field conditions? As far as custom actions go, is there usually a choice of extractor type? Have makers generally agreed on the "industry standard" extractor, and all generally use the same type? Or will the choice of extractor possibly mean having to choose one action maker over another?
