One thing i have noticed in the brief time i have been shooting these rifles, is the Omega seems to be more reliable than the Accura, when shooting BH209. I attribute this to the shape of the barrel end of the breech plug. Both plugs appear to be set up to use pellets, however the Omega breech plug has a larger concavity in the end. To me, it seems this makes for a more reliable BH209 ignition.
So, to answer your question, i think a breech plug with a significant concavity in the end is better than one without. There is very little data available to me, so this opinion is some weak.
As far as blow back goes, the Accura is some better than the Omega, but the Omega will continue igniting the powder after it gets carboned up, and starts 'blowing back', whereas the Accura will hang fire or misfire, if the breech plug carbons. Normally, i let the Omega tell me when it is time to drill out the fire channel, but i don't dare let the Accura tell me, because it will misfire, and cause me loss of food.
Ron, I think Sabotloader mentioned something as you about the style of the BP's in the Knight's with the concave BP Vs the Flat one. But is your experiences with just using BH209? Also how long between shots do you go with your ACCURA befor you clean the BP? I normally go about 20 shots at the range with no problems and I've never had a hangfire with my ACCURA's. I know BH209 does really carbon up the BP so the BH may be the problem there.
Since Sabotloader talked me into using Teflon Tape on my BP, the blowback on my ACCURA's have been cut in half.
