I recently acquired a Redding/Saeco lubrisizer to resize. 349 diameter bullets since neither Lyman or RCBS make a 349 sizing die. It's a little different than my Lyman and RCBS lubrisizers since it has a heavy duty pressure spring inside the lube reservoir. I assume I can back off the spring when I'm done to release the pressure. The instruction manual is laughable to say the least. Anyone here with experience with one of these?
