Drew;
I note that either 28 grains Ballistite or a 3 dram measure of Dupont bulk smokeless with 1 oz of shot are recommended loads in a 1913 Lefever Arms Co catalog with no mention that they should not be used in their Twist or Damascus barrels.

I would certainly not recommend using such loads in 100+-year-old guns (Steel Barrels Included) & even then not every one loaded this heavy, but obviously, some did or these loads would not be noted.
