Handy rig to have, but barrel hardness is seldom an issue. More of an issue for those doing the rifling.

Good job of making the video. No wasted fluff at the beginning and good presentation.

Mark makes great videos!! Mark also touches on some of the following information in another video.

The "issue" is with old barrels that folks claim is a must for shooting certain smokeless cartridges such as the 38-55 and 32-40 of which both were loaded by Winchester for use in three groups;

1. Black Powder - Low Pressure, Low velocity...normal steel barrels...basically anything under 30,000cup
2. Smokeless Powder - Low Pressure, Low Velocity...normal steel barrels...basically anything under 30,000cup
3. Smokeless Powder - High Pressure, High Velocity...special steel barrels...basically anything over 30,000cup

It is these issues that the discussion about "Special Steel Barrels" being standard or special order...


If I recall correctly, Whelen Townsand wrote of such and added to by 1918;

1. Low Power - up to 1,750fps - although some velocities and pressures not suitable for weak design rifles.
2. High Power - greater than 1,750fps - Although not always stamped on the barrel, special steel barrels needed (bore wear issues, not strength issues), 30-30, .303 Savage and the high power loaded 32-40 and 38-55 loads.
3. High Intensity - Velocity greater than 2,400fps, - 30-40 Krag (30 Army), .30 cal. 1903, .30 cal. 1906, etc.

Here ya go. Hardness testing is important on actions, measured just below the lug seats. My Wilson Rockness tester below with the big BBK Magnum action. 34 on the C scale, a good number.



A M98, think it is a Santa Barbara. Not an action for that hot 300 Mag.

I was sure hoping this would bring some others into the light!!!

I’d like to see him also test those same barrels with an xrf gun to determine composition
While hardness is important, steel composition is important as well and annealed 4140 can be similar in hardness to mild or nickel steel.
Maybe the “proof” or “nickel” was simply a trip through the heat treater
