My f/Tr rifle is built on one of the early Prarie Gun Works Coyote single shot actions. These actions are a 2 lug design, and have a sako style extractor. Mine sometimes decides that it doesn't want to grab the rim, and then I'm stuck breaking position and doing the cleaning rod tango on the firing line. Is this sort of extractor adjustable, or do I simply need to be extra anal about cleaning my bolt face after each relay?
