When I first saw them, my thought was that they had been pushed into the case, meaning the sizing and crimp weren't sufficient.
They are way deeper than they need to be. You want the side of the SWC to contact the feedramp at the same location as a RN-FMJ. Yours are about 0.10" too deep.
I use 1.190-1.200 OAL with my 170-175gn L-SWC. The shortest I have seen referenced was 1.130.
The dings could by at the feed ramp to barrel interface (assuming it is not an integral feedramp barrel) or you left the cases without sufficient taper crimp.
