Sat down to trim some 6mm Rem brass last evening and found that the fine adjustment bushing was somehow locked up with the lock bushing, i could not separate them with two pipe clamp even after soaking overnight in penetrating oil. Unit is still functional, but a pita without fine adjustment, Called RCBS to inquire about purchasin general replacements, but they are apparently still sheltering in place. I know Google is my friend, but I'm coming up blank. Perhaps God is telling me it's time for a power trimmer.
