SWThomas, i hate Federal Primers with a capital H. My favorite primer is a standard CCI by far. The reason i use Federals with BH209 is because it's the only primer in all temps that has not failed. When i walk into the woods, it's with stuff that has been tested and proven to work in all conditions.

The Reminton STS and the standard CCI (You weren't specific)failed in cold temps in T/C'S and Knights. I did not test the CCI-M this past winter. My findings are based on hundreds of shot's from temps in the range of -14degrees to 70degrees.

Please dont assume at other peoples cost.
