Stainless Steel Barrel Life

410 and 416r stainless steels both have a lower sulfur content making them less prone to developing sulphide stringers which may.

Stainless steel barrel life.

Ss is a bit less tolerant to abuse and throat erosion than carbon steel. Continuous mag dumps and barrel overheating will fuck things up quickly. I recently compared two sets each of nitrided and untreated stainless steel barrels. It is a high carbon content steel which makes it resilient to high heat scenarios and with its abrasion resistance the barrels wear slower over time.

The machinability of stainless steel is much greater than that of chrome moly steel and due to this fact the surface finishes will be much smoother and this is most important in the throat of the bore due to the fact that this is where fouling begins and the spread of impurities throughout the barrel. Conservative rates of fire will yield long barrel life 20k. 416 r stainless steel is stainless steel formulated specifically for gun barrels. Button rifling medium contour 16 inch match 308 win.

So stainless steel fouls less and is. Barrel life guidelines by caliber and cartridge type as a very rough rule of thumb i would say that with cartridges of 222 remington size you could expect an accurate barrel life of 3000 4000 rounds. The thicker walls of a medium heavy or bull profile barrel will strengthen the barrel and make up for the shortcomings of 400 series stainless steels as a barrel steel. 416 r is stainless in name only as it is still susceptible to corrosion but at a reduced pace.

The barrel configurations were identical.
