What criteria do you use to discard brass for reloading?

[CINDERS]

Some collectors are scammers trying to drive you down so they get a good deal, I pay a fair price for stuff do the research on going prices and go from there pity your there I'd be there in a flash to have a gecko I did get taken for a ride from a friend some years ago who offered me a bulk lot for $XXX.oo's as he said it was a substantial lot (Not) and when I had sorted it it had a few choice pieces (3-4) out of 200 the rest were well bloody shite.
There was a chap who passed a little while ago an old gunsmith and had a really good selection of rare cartridges and ordnence very nice indeed I offered him a substantial sum of $4 thousand dollars well above what it was actually worth but I really wanted that collection it really had some very rare gear, in the end my friend swooped on it paying half what I offered and then skited about it when I asked him how much he paid.

Bit wiser now.....I am still friends with the chap and have brought other gear from him but call his bluff and walk if its to high he usually comes around. If I find stuff I shut my trap until I can poke it under his nose I mean at last count he had over 200 rifles & shotties in his collection!
