ref: Triumph plug
Taken from the Western Powders email:
Our guys in the lab are pretty high on the T/C Omega with the regular breech plug, not the quick release."
Obviously Western does not think so as they are having a problem with that one also.
Ron for me the 1/8 flash channel builds carbon faster than it needs to. Opening the channel to a larger diameter really slows down the carbon build up. IMO, one of the reasons the Soeed Breech works so well is the length of the flash channel increases it's abilty to hole more gas. The .028 flash hole will work, but i believe it is a proven fact that .032 will work in a wider range of temperatures and weather conditions.
The other thing I find is that I can use the cooler primers and avoid the quick build up of carbon and get less potential for gas cutting on the nose of the BP. The vent liner virtually assures that you will not ever gas cut the nose of the BP.
I am on the road right now so there is not much as far as picture information that i can share with you.
I can share that the size of the flash channel is a key asset in making a univerally acceptable all powders, long lasting bp and reducing the blowback pressure on the face of the primer. You may see this re-emphasized in the new breech plugs that will be coming on the market on a later date.
One of the things i can share is that we have found with the increased size of the flame channel and the inverted cone shaped nose on the BP pressures at the primer have been reduced.
