But if the bullet would hit the lands, i "should" see marks of that, right?

I don't think i noticed any, but then again, i didn't look for em either.
I'll make sure to check if it happens again, and if it does happen again, i'm keeping the problem round for post analysis.

Cleaned my brass today, all tumbled, deprimed, flash holes cleaned, lubed and ready to do a batch tomorrow.

I also got me digital caliper, had a regular one, but that's to slow to measure more things in series..

Already measured a number of shells from tomorrows batch, doesn't look like case length is an issue at all, they are all well within tolerances, there is no noticicable stretch after been fired twice (1x factory load, 1x softer reload)
