Sorry this is a little late. Take a look at an ultra sonic brass polisher. They are about $70.00 at Harbor Freight Salvage, up to $200.00 everywhere else. Use 50% distilled water, 50% white vinegar and a couple of drops of dish soap. Run for about 5 minutes.
This cleans out the carbon build-up on the inside of the case which results in more consistent pressures. This isn't important to the average shooter but if you are shooting competitive long range, it is important.
