I happily load slow on an old single stage Pacific. However, I thought I'd speed things up a bit with the primer feed tube system, which fits my press perfectly. That thing has given me fits though. I have it all set up, to do what it is supposed to, but 75% of the time when I pull the pin to release the primers, they jump the little spring pin and dump all over my reloading area. Having little primers everywhere makes for a frustrating day. I also had to sand and polish the tube end quite a bit to get it to seat in the assembly. So I'm loading and placing the primers in by hand, one by one while the tube sits on the back of the bench and laughs at me. Any advice appreciated, the spring assembly is delicate and I don't want to go bending things without knowing what I'm doing. Thanks!
