Two possibilities come to mind.
1- that isn't cable housing, nut hydraulic line, and therefore lacks compression strength altogether. This is easy enough to confirm by looking at the ends which should have a circle of steel strands cut end on. Anything else, ie a bunch of thin strands, vs roughly 15-20 rigid wire ends, and it's not cable housing.
2- you used the wrong style ferrules, with conical bottoms, and the structural strands are pinching toward center and extruding through.
Just looking at the outside, I lean toward hydraulic line, but that's just based on cosmetics.
It was definitely Jagwire cable housing. It was new in its package. I did substitute a ferrule going into the STI lever because I did not like the looks of the stock black one exposed. The tip of that replacement Ferrule does look a bit damaged now that I look closely. But I also have cables sticking out of the other side that had the stock ferrule? I will try cutting this one down and installing it with the correct ferrule. If all it was, was my stupid taste causing this, I will smack myself very very hard.
