I'm a tapper as well. I'll fill the measure, tap it twice then top it off. Swing the swivel and pour down the barrel. As nchawkeye said, I also do the barrel tap to level the load in the barrel prior to seating the projectile.

I wonder what the difference would be in a tapped load and an untaped load over the chrony?That sounds like a project after the deer season.Which one is more consistent (velocity wise) will be the main focus. Velocity consistency should relate directly to accuracy consistency. Test date is mid Dec....stay tuned folks.

When they do ballistic loads for books, I wonder what they do?????
