Handgun Reloading

[givetoget]

Ive reloaded a lot shotshells before but never handgun rounds.I will be loading 38/357-9mm-40sw-45acp-45colt-454 casull, First ? is how do you determine what length to make them. The reload data i read shows an Max OAL and Minumum OAL.How do you decide when every type and weight of bullet is going to differ. 2nd ? is can I reload 454casull with the 45 colt dies (i am useing Lee dies) I talked with a reloader and he said sure, i talked with Hornady and they said you should be able to and Lee company said no you can not they differ slightly. I am using 700x powder is there a better or cleaner powder I could use. And any other tips and advice would be welcome. I do have a New Hornady data book and a older data book but dont recall name. Is there a data book that would suit my very needs. Sorry for being long winded but i wanting guidance so I dont make a mistake.

Thank You Very Much,

MM

I would suggest a good reloading manual or two and read them front to back. It will answer a lot of your questions. Not just the powder load data.

Sorry for not answering your question.
