Variflame II Omega Breech Plug???

[Hulions]

I just ordered a Variflame II breech plug for my TC Omega. My local gun store has Large Rifle primers in stock but no Large Magnum Rifle primers. I am currently shooting 84 gr by weight (120 gr./volume) of BH209. Using this load, will the regular Large Rifle primers work or do I need to have the "Magnum" primers? On the EABCO website it said to use the Magnum primers when using BH209. What do you guys think? Have any of you used the regular Large Rifle primers with BH209? Thank for any advice and help in advance.

Ive used large rifle primers and large pistol magnum primers with bh209, successfully. If you've got a well sealed breech and bullet, then even a regular small pistol primer will probably work.

Do you not have the factory plug ?

I seen some o rings do you need these to get a good seal

Yes, I have plenty of the regular 209 Breech Plugs.

The best way to find out is trying it on the coldest day you can. then you will know what works with your set up. If in doubt just use your stock 209 plug with Federal 209A or CCI Mag primers. The powder is named BlackHorn 209 for a reason, it's designed for that primer.
I don't believe you will gain any advantage with the Variflame breechplug.

It's my understanding that the 209A is actually hotter than a LMRP.

Could be. Although probably less or the same temp. A 209 has twice the gas volume. I’m not sure if the temp data below is a mag 209 or standard 209.

I have a theory/belief that they are only needed for a less than perfectly sealed breech. They are very hard on flash holes and leave a ton of very hard buildup in the flame channel. Once you get a good seal on both the bullet(sabot) and the ignition source and have a short flame path, bh209 (and smokeless loads) are a lot easier to light reliably.

I bet a #11 mag would light bh209, if you could keep it tightly sealed. Which would be very difficult, and hardly worth the trouble with all the other options available. But someone creative and bored could probably do it.
