Just wanting opinions/ experience with free floating bolt heads such as Bergara Premier and Savage. My question/ concern is that it seems like every time the bolt was opened, any lug grease applied to the locking lugs would be scraped off by the gas shield because of the tight fit between locking lugs and gas shield . I had a Weatherby gall the locking lugs so I'm paranoid of not having grease on the lugs... Any thoughts?
