Madhouse Posted April 13, 2014 Report Posted April 13, 2014 500 rounds of tumbled, polished 5.7x28mm brass, shipping from Houston $50, OBO
Madhouse Posted April 13, 2014 Author Report Posted April 13, 2014 Well, I'm told tumbling is not a good process for 5.7 brass because of a coating on it. I guess I ruined this batch...??
planeflyer21 Posted April 13, 2014 Report Posted April 13, 2014 I've not heard that about any brass before, including 5.7 brass. You'd think one of the many people reloading it would've mentioned it.
Robocop1051 Posted April 13, 2014 Report Posted April 13, 2014 What coating? I've shot hundreds of that stuff. I don't remember any coating... I'll scratch a round as soon as I get home.
starfury Posted April 13, 2014 Report Posted April 13, 2014 Yeah they have a coating on the brass. It’s necessary for it to feed reliably through the PS90 mags (it is a straight case and it lowers the friction). I clean them with simple green for about 5 to 8 mins in an ultrasonic cleaner (or you can hand shake them in a sealed Tupperware – don’t want to go too long or the ultrasonic cleaner will start taking the coating off too.
