9f Damascus special imperial or Krupp steel
O excelsior: Damascus or imperial steel
Seems they are claiming obviously different Damascus and Krupp steel grades?
The gun that I have has massive thickness at chamber .130 at forcing cone, .120 at 4” .70 at 6”, .048 at 8”, .046 at 12” down to .032 at 16” all the way to the end plus the chokes at 30”
Gun weighs 7.75 lbs.
Dean at skeets says it hard steel
I have read alot on the subject and have used formulas.
One mark has been removed by others but sure looks the same size and length ( can almost see the H) as my LLH marks on my other belguim guns. But this is a real stretch could be freak tool mark.
I have shot 10k psi reloads in gun but have moved down to 7.5k psi 1 1/8 loads.
Sure would like to shoot some wood ducks with this animal but I like my fingers.
Any idea what 1904-1905 LLH steel tensile was? I haven’t been able to find?
I would be happy to share other barrel marks from belguim guns but I think you have covered them well.
I do have a 1927 belguim gun marked Siemens-Martin steel on top with other guys like LLH marked on bottom but that seems very common.
Thanks
I do appreciate the work and information you and the other gentleman have provided.
Mr. Raimey has been particularly helpful over the years.
