I want to resurrect this thread because I'd like to know how people's Suomi conversions are running. Any bulged brass?
I was looking long and hard at the extractor notch on the Suomi. Is that made in such a way that on a Suomi the cartridge is fully supported? Or is the notch only exposing the web of the brass? I'm worried that my use of the Suomi barrel with an AK-74 action won't support the brass like it is in a Suomi and there will be bulged brass as a result... ?
