Contrary to current internet belief, bolt heads are NOT "harder than the hubs". The extractor installation wasn't 'slick', but that mess can be cleaned-up with a mill bastard file and a bit of wet & dry paper. No need to go back to your Savages, just beware of any used rifle of any manufacture. Lots of 'wanna-be' , unscrupulous types about. Know what you are buying. I can tell, without removing the barreled action from the stock, whether the trigger is an aftermarket or not. Examine the details of the rifle (any firearm) closely to avoid being taken advantage of. Don't blame the rifle manufacture for the deeds of an unscrupulous seller, blame the seller for misrepresenting the item.
