"Opinion" on high rd count pistols and steel cases:
1. A friend loads 9mm major power factor/hot loads: He "missed" culling the S&B steel case that is thinly copper coated and "looks" exactly like brass. When the round expanded in the chamber it jammed....hard... and couldn't be cleared without tools. He now always passes a magnet over all range pick up cases.
2. I reload minor power factor 9mm. After about 10K rds the pistol's polished feed ramp is just lightly scored where only brass and copper hits.
Steel is harder than brass. The scoring would have to be worsened with a harder metal hitting that same spot on the feed ramp.
I choose to lessen the friction and difference in expansion characteristics of steel.
