I'm 40 but I'll laugh, thumbs up and watch anything that says lube.
They make a .251 version.Unless that .25 slug come on different diameters.. if they are only one size .. it doesn't work on a standard .250 barrels I have 3 .25 barrels 2 LW .. 1 TJ.. they will slide through without almost no resistance from side to side .. completely unusable . At least on my barrels
