“Die threads are typically 1/14 pitch. That means an entire turn is 1/14th or 0.07 of an inch. If you go for .001 bump, it's hardly any additional turn at all, 1.5% of a turn, roughly’
Then comes the index marks and black marker.
1 Turn = .071429”, then comes the wild guesses, when will someone have an epiphany and discover the art of verifying. Verify, as in verifying an adjustment, instead of taking wild guesses in percentages of a turn or fractional turn in degree, simply go to the verifying tool, the feeler gage. Use a leaf from the feeler gage bundle to adjust the die off the shell holder, then secure the die with the lock ring, again, when securing the lock ring hold the die to prevent it from moving.
