Case tumbling

[waterford103]

Just bung 'em in a sock, and put 'em in the washing machine. They come out shiny and clean, and any nicks - if any - that the cases pick up in the machine will be corrected by the sizing die.

This is exactly what I do ,modern detergents remove all the crud .I use an old bank cash bag with drawstrings ,the missus doesn't mind either so long as it goes in with my clothes ;¬))

Never done it - over a season, my 6PPC benchrest brass will get about 40 firings - accuracy is not diminished. However, I do clean primer-pockets and case-necks - inside and out.

That is exactly the way the Vikings brass is treated and it does not seem to impact accuracy.

My main purpose behind tumbling my brass is so that I can give them a good inspection, any defects are not hidden by dirt.

Also shooting predominantly cast at all ranges with everything from cat fart to full velocity loads a build up of lube can occur on the case so I like to avoid that by tumbling, Can't be arsed with wet tumbling and it gives little improvement on dry except for my BP cases which are wet tumbled in ceramic media.

Just to throw my tuppence in, as I am now the wrong side of 45 and my eyes arent getting any better I have been using this stuff for a while now and find it excellent.

For me at least, it takes out a lot of the uncertainty of "is it a crack forming or isnt it" (my new varifocals help as well!) and I find it quite reassuring when reloading for my 577/450. I havent found a crack yet on the 'big brass' but have tested its effectiveness on 308, 223 and 8mm Mauser cases and any flaws show up quite convincingly. Its not cheap but a can goes a very long way-there are cheaper versions available at welding supply companies but I cant vouch for there effectiveness.

A couple of decades ago I didn't bother cleaning cases. Didn't notice a split, which scored the inside of and ruined a FL sizing die. Then I used to put them in an old pillow case and give them a 40 degree cycle. Didn't check properly that the cases were completely dry on the inside and ended up with some ruined loads because of damp cases.

Bought an Olsens tumbler. Still got it. Sonic, wet, stainless steel filings...... Because of experiences long before the internet and what have you, ten a penny newest fashion, I'll stick with my Hannams, polishing walnut media in an Olsens, thanks....
