Blow by from the chamber, lows are probaby lower pressure and don't force the brass out all the way to the chamber walls fast enough or completely, thus the blow by.

There is some blow by with all cartridges till the seal is complete. However lube and carbon are worst with lubed cast bullets.

Hope this helps!
