Unpopular opinion: that $180 wireless load cell I bought for blind picks is gathering dust, a $12 bubble level off Amazon has done more for me | Crane Operators - Vivisector
A $12 bubble level only tells you if your press is level, it does nothing for the actual seating depth error that comes from case neck tension changing between batches. The whole point of a load cell is catching the pressure spike when your brass work hardens after five or six firings, which no bubble is ever going to show you. You probably just are not shooting far enough for that 0.002 inch spread to matter yet.
