Its not harder than loading for my 9mm. It is more involved though. There are extra steps. Here is the abbreviated steps I do:
de-prime
lube
resize
trim
chamfer inside/outside case neck
optional but I do them:
De-burr and uniform the flash hole
clean the primer pocket
So, just a little more involved and my first shock was the powder difference. Going from 4.5ish grains for a 9mm load to 27ish grains for 223 made the powder go really quick. Maybe 250-275 rounds per pound of powder. You can make yourself ammo that will shoot better than any off the shelf though. If you are going to do this start buying now and in bulk if you can. Its like gas, buy it while its still cheaper than tomorrow...at least until the war ends and then I bet we will have surplus GI 223 coming out of ears. Also, a really good die set is the Lee Pacesettr because it also comes with the Lee factory crimp die which is awesome. If you live near someone you know that loads rifle you should go watch/help him one day and see if you really want to try your hand at rifle loading. Like I said, nothing to be intimidated by, just different.
