You are right, there are different opinions for sure. The flat on the end has nothing to do with it. The Knight Vision plug is flat and it works fine with hotter primers. The Omega Encore plugs are very short. And to boot they have that concave that you are talking about. What that means is, BH209 is really close to the primer. That's why i believe they are reliable. The Knight Elite's/Extreme's have the same concave in one of there plugs. That's why they are reliable. The powder is close to the primer.
You can take any breech plug on the market, and make a 5/32 flame channel to a .031 vent-liner and it will shoot BH209. No problem at all. The Concave is not needed at all. I will say, i like the concave because i do like my powder as close to the primer in any ML or Rifle.
These are my opinions and i have tested all the way's mentioned many times. The powder does not care what gun it's in. The breech plug is the key.
