tumbling brass???

[tnctcb]

i sized some brass for 35 whelen. then i put it in the tumbler and when it came out the top edge of the cases were bent like it hadnt been sized.i am going to size it again and clean it again but i am wondering if i tumbled it for to long or put to many cases in the tumbler.( only 50) what might cause this???

How much media was in the tumbler? I've never had that problem but maybe we can figure it out.

I've had that problem when I used too little media in the tumbler and the case necks where thin. I haven't had that problem since switiching to the vibrator style years ago. If you necked up 30-06 cases to .35 the thinner neck may be more prone to bending.

my tumbler has a fill to here line about half the depth of the bowl and its full to there.i sized the brass again and cleaning it now. ill see how it turns out. this is the 3rd lot of brass i have tumbled with this media, how often should i change it or just add media as nessacerry

I don't replace mine very often..just add media as needed.

Change it when it gets black.

maybe i had tumbled it for to long. after i sized it again it came out of the tumbler in good shape
