There only 2 ways to be sure you're doing everything right before attempting to fire a hand loaded cartridge. First of all:
Handloading RULE #1: Check everything at every stage of the process. Check, double check, and then check again. Don't be nervous, but don't be so over confident that you overlook something.
You could try and find an experienced loader near you who might be able to take a look at your porocedure and tell you if all is well.
