i wont trust a cooler primer, especially in colder temps. Its fine to play around with them on the range, but come hunting season, the cci mag is all i will use.

My cva ignites bh209 fine with those medium 686 primers but accuracy was horrible.

Buy a TC.


Besides, our ML season is hot.

Not to cause an arguement... the Omega plug is a good one, but it would and can be better for BH is the flash channel is opened to 0.159 vs the 1/8" that it is. Allows the primer to work more effectively and cuts down on the build up of carbon in the flash channel.

The addition of the vent liner helps in more than one way. It will stop the errosion and gas cutting of the flash hole by primers and the hot gases that BH creates. The Omega plug is not the hardest material in the world. The cone shape of the vent liner sheds some of the blow back of gasses and solid materials in the bore off to the side instead of directly back into the breech plug again reducing the amount of materail and heat trapped in the flash channel.

As Ron says the geometry of the plug is optimized, or something like that. But the plug does just plain operates more effeciently.

And again thse are just my thoughts - certainly does not have to be your thoughts.

With an Omega plug the powder is almost directly on the nose of the primer. If the plug is clean cold temperatures will have no effect on the ignition of BH. Western has now even published some BP guide lines and now they even understand what I have been saying for years. The length the flash has to travel is the biggest problem in igniting BH in cold temps.

I've read a bit about BP lately. It seems one of the advantages of the Omega is how short it is. Some complain that you need a tool to remove it, and it's hard to put on the primers. That's what makes it so good for BH 209. It's short. Make it quick release, and it gets too long.

I'll think about your mods. What do you charge?

As Ron said someplace... For you and you only this time, the total cost will be what it costs me to ship it back to you...

Muley Hunter

Hmmm....I give better than I take. I appreciate the offer.

Let me think on it.


I'll use PM's from now on about this.

Yep.. that is best

There is no doubt that increasing the flame channel diameter of the Omega breech plug to 5/32" or 0.159" makes it more better. I have proven this to myself. Making this change is not detrimental in any way, but it does have the advantage of allowing more shots between cleaning the flame channel.

If the flash hole of the Omega plug is not worn, there is zero advantage to installing a ventliner. One day the flash hole will be larger than 0.032"; when this happens, it will be time to install a ventliner.

The OEM Omega breech plug will ignite BH 100% of the time; nothing can be done to it to make it better than 100%.

i like the 5/32" flash hole. Shoot all week long without having to clean it out.
