Replaced gasket, drain plug still leaks

So I finally got new gaskets for my oil drain plugs (ok, well a couple months ago).  Autozone only had copper (the ones I removed were plastic)  but they don't seem to be any better than the old, spent ones.  The plugs are torqued to max spec, which doesn't even seem to be enough to crush the copper IMO.  Think the copper is the problem?

what i do with a troublesome drain plug is after you drain the oil and put the plug in is to clean it with carb spray dry it off really well and seal it with ultra grey permatex. works good.

I prefer nylon (plastic)  plug gaskets.

Most quickie oil change places keep a small stock of them
