I use a simple loop of paracord burned together to keep my press handle from falling down when somebody bumps it
Dropping washers on powder to help even out powder throws comes to mind.
A couple washers duct taped together, with a string to get them out, dropped on the powder in the tube helped to even out powder charges.
Some powders just don't meter well, this is a 'Trick' that is cheap, effective and helps with most powders that don't like being dropped.
+1 on J. Morris!
Stupid simple and saves a CRAP LOAD of time!
When I first saw it, it was a face/palm moment for me, it was just SO SIMPLE & easy it just escaped me.
