Selecting from 1% resistors

[George Herold]

I want a 500k resistor 0.1%. It's a prototype so metal film through hole resistors.
I got out the bin of 1 Meg 1% er's figuring I could find a pair.
They were all high, 1.005 Meg was the lowest and 1.015 the highest,
with most above 1.01.
(And yes my meter works, I've got 1M 0.1% in surface mount and the first one read
1.0004 Meg)

I got a 499k and put 1k in series, works fine...
just disappointed there's not a "better" spread in the 1 Megs.

the closer to spec ones are probably sold as <1% tolerance units.
