We know about exceeding 'max loads'. How about exceeding minimum loads?

[Jim Watson]

There is nothing scientific or magical about VV’s starting load, it is just 90% of the maximum load. Not necessarily a minimum load.
I would be comfortable working down to the desired velocity. If it gets erratic, stop.

@Captain*kirk
Your best bet would be to follow @Walkalong suggestion in post #3 and call VV customer service line..
Re-assurance directly from the manufacturer would settle your dilemma better than banter from some of us internet yahoos…..

This.

Especially the part about "... If it gets erratic, stop. "

This is why one needs a chronograph. When the ES starts widening, that shows erratic ignition. Stop reducing, and go back up the scale.

I had thought this was common practice, or at least common knowledge.
This is what "working up a load" means. Watch the target, watch velocities, and watch velocity spreads.

I’ve trimmed the thread, let’s play nice please

I’ve used the phrase, “Working down the ladder,” as a holdover from my younger days and what “the old guys” back then told me but, basically, it is working up a load but going lower on the charges is same-size steps from Start instead of higher.

Yes, erratic is bad. So are bulged primers.
