    Hi fellas, is it a good idea to clean inside the case and case neck every time you clean deprime and resize your brass. I haven't in the past because I didn't think it was necessary.

    yes, ill run a nylon brush of applicable size in and out one time weather or not the brass is going in the vibratory cleaner or right off the resizing die.

    Yes, Waynzee, IMO it's good practice to clean the inside of the case necks. My preferred method is to run them through the sonic cleaning cycle and, while they're still wet, chase the necks with a nylon brush before dropping them back into the cleaning solution for a brief re-wash - then rinse. I brush the primer pockets at the same time.
    If I'm not using the sonic cleaner (when using the dry media vibratory tumbler) I still run a brush through the necks before tumbling. Only difference is that for a dry cleaning I use a bronze brush.

    I also use a sonic but when they are finished there is nothing left in side the case or primer pocket to brush just rinse several times and dry....

    I sonic vibrate until clean usually about 1 hr.

    Using 1 big heaping table spoon of lemon shine and 1 heaping table spoon of dawn dish soap per 2 guarts of heated/hot water...

    Thanks guys, what would be the benefit cleaning inside every time ? I should mention that I use corn cob media in a Lyman tumbler, old school but it works, just takes a little longer.

    Switch to very fine walnut shells found at petco under lizzard bedding ,,,, you will never go back to corn cob... and no more plugged flash holes EVER and cleanes better than corn cob !

    Absolutely. One of the advantages of the liquid stainless tumbling media is that the insides end up as clean as the outside of your case.

    This gives you a much more positive seal when you seat your bullet.

    When I first started reloading I never bothered but eventually figured out that by not doing it I got inconsistent neck tension and moisture could much more easily contaminate my powder.

    Believe it or not I've found that if I'll tumble with the steel pins and just plain water for about ten minutes and dump it just for a rinse I can reuse my cleaning solution several times which makes it go a whole lot farther.

    I use the nylon before sizing all the time. I have found bullets that I pulled on rounds that I reloaded before I started cleaning inside of necks , were very tight and hard to pull out. This is meaning is that chamber pressure would be higher with tighter bullets in non-cleaned necks. Also you can hear the expander rubbing inside the non-cleaned neck.:)

    Since I got a sonic cleaner, I clean every 2 or 3 firings and nylon brush out the necks well in between. The expander rubbing is a good indication it's time for cleaning.

    So let me see if I got this ya'll tumble your brass to remove the carbon build up inside the case neck then put carbon back inside the case neck before seating your bullet. Huh. :D

    Tumbling in dry media does.not remove the.carbon. wet tumbling or ultrasonic does.

    Do whatever you think best.

    Many benchrest shooters wipe the.outside of.the.case off.with ballistol which they use for case lube and hit the necks with a brush.

    Well, Waynzee, it's not actually "carbon" - it's graphite that some use to lube the inside of case necks. I used it a couple of times; didn't like it. I used a very light film of RCBS case lube, applied with a Q-tip on every other case when using the neck expander mandrel then rely on the residue from that to act as a bullet seating lube. I've seen guys who apply neck lube like they were greasing a wheel bearing ... it ain't that critical; and it tends to foul powder.
