The length of the flame channel in the plug is the same as the OEM plug. In the plug that utilizes the o-ring the one end of the flame channel is rubber i.e. the perimeter of the flame channel for about 0.75mm is the compressed o-ring. The flash hole at the end of the breech plug can't be much larger than 0.034" because that would allow granules of powder into the flame channel.

The hole in the end of the adapter is similar to the hole in the end of the shotgun primers. If one wants to say there is two flash holes when using rifle primers, then one could say there is two flash holes when using shotgun primers. The flash hole in W209 primers is about 0.092". The flash hole in the end of 209A primers is about 0.102" The flash hole in the PR Bullet primer adapters is about 0.082".

I just received and shot my PR Variflame II breech plug today. Super clean after shooting and instant ignition with loose fitting sabotless bullets in my .45 Match Grade Machine Encore barrel. I used Win Large Rifle Mag primers in the carriers.

This is a close up of the primer pocket. Just a slight dusting of residue at beginning of flash channel after 10 shots. Zero blowback!!

There is no way a loose fitting sabotlless bullet will ignite with BH209.

You MUST be fibbing.

Oops wait a minute...it did ignite for me too in my Pacnor45 after i used a arbor press to compress the powder and bullet. J/K i didnt need an arbor press

No fibbing

With the short flash channel and deep dish in the Omega plug I had no doubt it would fire.

I snapped one Win Large Rifle Mag primer for testing on the clean barrel and it makes a lot of spark come out the 28" barrel.

Myself, i will be very interested in reading how the flash hole endures when shooting powders other than Blackhorn. The flash hole in my breech plug has not grown even 0.001" in over 700 shots of Blackhorn. Yes, i am very very curious to read how the flash hole of your plug will wear, shooting other powders.

Ron,

I will let you know how many shots it takes to open to .035 as I have a bit that size that I use to check vent liners with.

Thanks for reminding me about the other powders. I need to clean the bore since I shot some BH209 loads thru it to start.
