There seems to have been a few threads lately that have brought to the forefront why a bump gauge might be a good idea. Or at least help with some answers.
I just started loading for a round that none of my current inserts will work with. I could order a new one, they are relatively inexpensive, but $10 USD soon eats a $50 bill pretty quickly with shipping etc. So to save time and money, I did this. This is certainly not a new idea I’m sure, but it seems to give a pretty accurate reading.
