My concern that something did go wrong seems right, now it crossed 20cm again and 15cm vertikal.
So i resolder it (again) and now its right in vertikal but still 15cm across. So tonight the torch springs to life again and the barrels will be spread.

Now this could be the powder charge, as when i checked some of the older realodings it seems as the powder messurer adds up yo 2grs when ever it wants. So perhaps i regulated it with a overcharged bullet. I have now uppgraded it with a baffle, but i will ceep a close eye on the scale.
