Try contacting Belden. They are a major manufacturer of wires. A contact I have in my card file is John Staates (a technical person, not a sales rep) in their product develoment group. His 800# (I can reach this from CALIF) is 800-235-3362. Another problem that might be causing part of your problem is the adhesion of the insulation to the metal. If this is subpar you'll have problems. Any reduction in X-sectional area will increase your resistance. Any deformations or cracks will affect the x-sectional area. The quality of any solder joints also could be suspect. If you have a "cold: solder joint" (a blob of solder without good electrical continuity), you'll also have high resistance.
