Repeatability is excellent. The smaller the powder the better it is. With WW760 is is dead on every time. With IMR 4895 it as also virtually dead on. With H4831 it is always within a few kernals of powder. If you are talking about hunting loads you will never notice the difference. I load IMR 4064 for my 500meter silhouette loads and throw directly into the cases just check every 10 rounds and have never seen a variation at the target, I can repeatedly break clay pigeons one after another, off the bench, once sighted in for the conditions of the day.
IMHO, You will not find a more consistent measure without paying twice the price. Consistency also has a lot to do with your technique. Make sure you do things the same with each throw, don't knock the drum back differently each time. I also throw all my charges at one time ie. don't throw one and then seat a bullet and thump the press up and down between rounds.
