Remington actions are strong, and the "three rings of steel" true to the extent that a chambered cartridge is completely embedded in steel. Mausers for example have an ejector cut through the bolt that allows gas to escape into the action, as does the bolt face configuration allowing cartridges to slip under the extractor hook. Mauser barrels also have a large cut in the chamber area to accommodate the extractor. Mauser lost an eye during early phases of development to escaping gas, subsequently equipping bolts with baffles to deflect gas away from the shooter.
The weak link in all of this is the brass cartridge case, once it fails, high velocity pressurized gas escaping through the action will wreak havoc on any rifle. Gas venting becomes the deciding safety factor in any action, Remington does it as well as any.
The Remington is safest with the original extractor, and compromised when the bolt is cut away for the Sako type extractor. This defeats the gas containment system.
Remington bolt handles are silver brazed to the bolt body, so they can be broken off, as when hitting them with an object when a cartridge sticks. Same with the post '64 Winchesters, where the bolt is two piece, and many others. There is a modification where the bolt is screwed down after sliver brazing.
Remington actions are plentiful and cheap. Bonus is that there are zillions of aftermarket accessories, parts and accuracy upgrades available for them. The 40X single shot action is a bit stiffer and offers a bit more accuracy when set up properly.
Remington actions that are completely reworked with all the bells and whistles and a high end barrel are accurate enough for anything except competitive benchrest. All in all, they are a good safe product with almost unlimited potential for modification.
