The pitting is severe.
When I was a kid, a few little friends in the neighborhood exchanged our thought on food. One kid told us that he only ate "lean pork without fat"; another kid said "fat is Ok, I can eat fat, but I don't eat pork skin"; yet the 3rd kid expressed "pork skin is eatable, but if it has fur on it, I could not eat it" (that's me
). The very last kid "I don't care it has fur or not, everything is fine with me".
For guns, bad pits are very hard to handle, buffing is not enough, need welding.
