I’m glad you got the issue fixed, and yes, taking care of ones equipment is always good advice, but if anyone wants to reread this thread they’ll have to admit you received some excellent advice, and anyone wanting advice on primer seating would do well to read this thread.So, after installation of a replacement primer feeder from lee, ive had 0 issues with primers so far (400 9 mm, 250 223). Keep your equipment in order, replace worn out parts and dont listen to ppl who have no clue what they are talking about (99% of this forum).
