Why tumble cases

Hello, I am getting set up to reload, and am wondering why people tumble their cases before reloading them.  If the brass is picked up from a relatively clean range, is there a need to tumble them before reloading?  I understand that if the cases were really dirty they could damage the dies.  For clean cases can I skip the tumble? 

The main reason to clean brass is to remove any dirt and grit that might damage the dies, and more importantly, might damage the chamber of your firearm. beyond that, a shiny case is slightly easier to resize.

AND..... Pretty ammo just shoots better too! I reload for CAS and most of my low power loads soot up some. I use a lot of Unique though. You really don't realize how much crud the tumbler takes off.

My tumbler does not clean the inside of the casings as much as the outside. Is that ok?

"My tumbler does not clean the inside of the casings as much as the outside. Is that ok?"

Perfectly fine.

One other reason to clean your pre primer punched brass is that some cracked or split cases are hard to see on dirty cases.

I soak my cases in cleaner drain, dry and sort. I then tumble and then punch out the primers. Clean the primer pockets and then the fun begins.

I suggest checking the inside of your casing after also. Im using walnut shell with additive that creates a lot of dust. You can reduce this by running paper towel squares in the tumbler or pouring the media back and forth between containers outside on a windy day. I didnt run papertowels maybe 2 times and I ended up with powder condensing inside of the longer casings.

This resulted in a 158gr .38 getting stuck in the barrel with a light powder charge. After shooting 20 rounds, I heard this really light pop and I knew something was wrong and the bullet was stuck maybe half an inch past the forcing cone. I pulled the remaining 30 and the all had a decent amount of red dust mixed in with the powder so now I give them a quick scrap with a small allen wrench and try to reduce the dust any chance I get. Lesson learned haha.

I use NuFinish car wax on my paper towels. Not only does it pick up the dust, but it also helps the shine and gives the brass a slick coating which seems to help it feed better.

Yes, if there is no foreign matter inside the shell casings, you may choose to skip the tumbling step.  Tumbling with some of Dillon's case cleaning solution makes the casing prettier and can help in their movement through the dies and into the chamber of your barrel.
