Send a pm to bulletman. He has used it for years and will be able to give you the straight goods. He has suggested loads to me often in the past based on Quickload and they have never been far off the sweet-spot I was looking for.
I use it and it is a great tool. You can simulate loads and what if scenarios.
Simulated results (speed) have been very close to what I have measured in range.
I bought it for +/-$120, now I see the price has gone up U$160. Not sure if its worth for the occasional or the one time loader.
