Also what exactly are the differences between standard 209 shotgun & 777 primers

I have not had enough experience with the T7 primer and the use of BH powder. Because of that I would tell you I would not try it without more shooting time especially in cold weather.
Western recommends MAG primers because they have to make sure the powder goes BOOM in all of the different breech plugs on the market. With a Lehigh or Lehigh/Knight BP there is not need for a mag primer. There is not doubt in my mind that I would shoot W209'w with confidence.
This chart shows the different pressures created by the different primers listed...
