I cast a few Flat Points with WW + 2% Tin, and they came out at 680gr (unchecked and unlubed) and at 0.5015". This is pretty much exactly where they should be - 20grs under seems like it's a lot, but it's only about 3%, and my alloy has a fair bit of "non-lead" in it.
The bullets drop nicely once the mold is heated up, and that takes a LONG time, so be prepared to cast a bunch at each sitting. The bullets drop well from the mold, but I had to re-tighten the sprue plate screw about every five bullets until I noticed that it has a set screw (dummy). This is a very nice mold and I will buy many more from them - quality, price, and speed of delivery are all excellent.
The second pic shows a cast bullet, seated 0.100" off-the-lands (2.500" OAL) for my NEF Handi-rifle, and then the Lee 440gr where I seat it at an OAL of 2.275". Very little powder space is taken up, as I can seat it out as far as I want, unlike with a revolver. In fact, I can seat it to 2.575 behind a driving band, and crimp in in place (once I get a crimp die). I'm going to try a full case of BLC-(2) and a few full or near full cases with other powders between it and IMR-4198 in burn rate.
