If using any rifle for such game I'd reccomend running the ammo in question thru the action to 'prove' their functionality, even factory.. I've had remington's for many many years with few problems.. That said I have had the extractors fail either temporarily or permanently but then I've seen even the vaunted mauser fail.. In that instance the extractor broke,..,the result a 'slow' single shot.. I advise anyone entering such a hunt to take a backup rifle along..just in case. The erality is though that there is little likelyjhood of a problem with a M700. Good luck and good hunting.. pictures would be nice!!
