Note About Hornady Powder Micrometer

[rdtompki]

I switched to this rotor insert not long after buying a Hornady LNL AP press (which also marked the start of my loading career). It's great for quickly making 0.1gr changes. One problem with the unit is the loosening of the vernier nob which is not indexed to the shaft. Once that screw loosens all bets are off. I spoke with Hornady today and, as expected, they suggested using loctite on the screw. Since the vernier is not indexed I'll need to position the indicator so that the "zero" aligns with the measurement scribe when the vernier aligns with one of the integer marks (e.g. 1.0) or one of the mid-marks such as 1.5.

The sizing micrometer doesn't experience vibration and hasn't loosed at all.

Yep, I've had it happen too. I was trying to dial in my powder charge and was pulling my hair out why I couldn't. Found out that it had loosened up on me. It never happened in the last 8 years or so I've had it. Now I watch it a little closer.

Happened to me as well. I had to collect a whole new set of data for my powder charges.

Is this powder micrometer needed? I've got along fine for years with just using the Hornady pistol or rifle rotor that came with my LNL press. I can change my throws as small of increments as I need to.

It's not needed per se but it does make it real handy to set a previously-used charge. Of course, ALWAYS verify them with a good scale
