Some cases are longer, some are thicker, some are cleaner? If the expansion die goes in that first time, it'll do the job.
I like bevel base bullets. You don't have expand the case mouth as much to get them easily started. You're also not working the brass as much, which should translate into better chambering and longer case life.
Since you're new at this, and many handgun calibers are sold with nickeled brass I'll also mention that while being nice looking, they don't tend to have a very long service life.
The nickel is harder, and doesn't take to well to being shot and sized many times before its hardness leads to cracks. Nickel being harder is also just plain harder to work with in general.
Trimming and chamfering nickel rifle cases ain't fun at all. I had one RCBS .243 rifle die that was scratched from a nickel bur. The burs shouldn't be an issue with modern carbide pistol dies, as they are much harder than steel rifle dies.
Any way enough on the nickel? If you're going to be loading handgun rounds the method you're using now is great! But it is very slow when doing more than a box or so it would become tedious for me.
I pretty much use a similar method to yours, weighing each charge for my hunting and target rifle loads. I load these usually in batches of 50. I load handgun stuff usually in batches of 100 or more, and the auto disk is a real time saver. As I've mentioned before, I had a Little Dandy from RCBS prior to finding the Lee measure. It worked great too, but it's still a separate step.
I won't encourage you to do anything that you're not comfort doing, but I can say that I wouldn't take $1000.00 for Lee measure if I knew that I couldn't get another.
Thanks chuckdog! It's great to be able to tap into the experience of people like you on the forum.
