Also Semisane, thanks for pointing me to LaneNebraska. I'm going to pick up about 10 of those.
Save yourself the trouble of a second order - get 40 or 50. I guarantee if you get 10 you'll want more. With something like 40, you can load 10 with 80 grains of powder, 10 with 90, 10 with 100, and 10 with 110, and be good to go for a range experiment with whatever bullet you're trying.
