not sure I really want to know any more, going to go shooting and try to wear out some rifles so my sons don't get everything good when I check out
This (all chinese) rifle is my beater and has seen close to 10,000 rounds over the past 4 years. Still printing the same reliable groups and still chambering and extracting fine.![]()

Perhaps they are having issues with the laquer coated steel case? The copper washed stuff is also available, and poses no problems I am aware of.
