I get having a very accurate chrony for working up rounds with powder burners. I also get using them for working with different pellets to see how they are performing. I also get using them for playing with regulators, springs, et al to see where a particular pellet has a sweet spot.
I'm missing something though. When one has a Thomas rifle with a 5 fps spread and isn't adjusting said rifle (the point of getting a Thomas, right?) and is using the same pellets and processes, what is the need for a top end chrony?
