I think the formulation and the specific rubber would affect the bounce height (resilience) as well as the hardness (durometer). One company used to make rubber balls of the same rubber, and one would bounce very high and the other wouldn't bounce at all because of the differences in plasticizer...
This site (http://www.oringswest.com/) seems to suggest that AMS-P-5315 is the same as MIL-R-5315.
Hope this helps.

One thing to note regarding the low, and high, temperature properties of the various rubber types is that within a type of rubber the low/high temperature properties can vary considerably.
For example, within the EPDM family, the ethylene (the "E" in EPDM) / propylene (the "P") ratio can vary...
