If you have the right breech plug inplace and it is able to breath you probably would not need to use those primers.

With my BP's and a vent liner installed I can ignite BH with a Win T7 primer or even a an old Remington 209-4.

If the Wins are working for you - even in the colder weather without a problem - stay with them. It really is not that BH is that much harder to start in clod weather but some of the heat from, your primer is lost warming up the flash channel and metal on the way to the powder... so a greater percentage of heat is lost in clod weather than warmer weather.
