Senior, I didn't know that. So the "nickel steel" proofing applies ONLY to the barrels? Receiver strength down the line is the same? I was under the impression the steel overall is stronger in the later guns.
My intention is to use cast lead only regardless, so does this mean I'm safe to load up the shells in a "non smokeless" type of barrel?
Yes
If your shooting cast, I'm thinkin you'll be limiting your fps to about 1500-1600fps. You should be quite safe. As pointed out there were 38-55 shells marked "Hi Velocity" these were box marked for Win 1894s, Marlin Levers etc. I have a couple boxes marked as such but have never chrony'd any I think they shot about 1600fps.
