Best method to clean cases…field tested and proven

[BushMaster-15]

Quickest cleaning I know of is Ultrasonic . Clean is one thing ,polished is altogether different .

Note Clean Brass , then polished . a weapons chamber could care less ,it's people who either must have jewelry bling for eye appeal or good enough to go for reloads .

Most shooters DON'T start with #60-70 year old left to the weather tarnished ugly brass cases . Mine have #27 firings on them and note ,NO ripped or chewed rims . ALL mine are .30 Cal M1 Garand specific . Last photo ran them in a Wet tumbler #40 minutes with custom solution and SS pins . As they've had as of yesterday AM #8 annealing's total ,I then ran them through to polish off the witness marks .

Think about a cartridge case as a super fine classic automobile paint job .
One doesn't spray $40K on a 120 grit abrasion job . Meaning in order to POLISH ,scratches and abrasions MUST be stepped out .

Corn cob or synthetic media will polish to a Higher luster ,than walnut shell ,as in the final polish .

I'm just not that picky ,as clean and somewhat polished is OK for ME . I prefer Load development and trigger time ,life's short enough as it is ,without excess prep fussing .
