Lots of different opinions on products. Thanks for all the replies. This turned into a longer thread than I imagined. It's probably more important that you use some sort of lube rather than what brand. It's also important to wipe off the excess so there's only a film on the interior of the action. You don't want oil or grease running into your magazine and getting on the cartridges. That would make them too slick to grip the chamber properly upon firing and increase the amount of rearward thrust they put on the bolt. So de-grease your chamber before shooting and wipe down the bolt and raceways after applying lube to get the excess out to keep it off your ammo.
