I would not get the one from western powders, it comes with an o-ring to put under the primer. I think I remember hearing they wear out after about 16 shots.
Here is the CVA BH 209 breech plug for about $5.00 less than you can buy it at CVA. http://www.lg-outdoors.com/proddetail.asp?prod=80873 you don't need a rubber o-ring.......

From what you wrote, i appears you don't understand the purpose of the o-ring. Western Powders furnishes the o-ring as a freebie. It is an option to help the shooter.. it is not required, it is an option. The same o-ring can be used in the CVA breech plug. What the o-ring does is seal the nose of the primer where it sits in the breech plug. This seal normally stops all blow by from getting around the primer.
A while ago, you wrote about, how to make this seal by shimming out the firing pin bushing so that the primer was 'slightly crushed'. Crushing the primer slightly, also makes for a seal against blow by. After you posted how to 'crush' the primer to stop blow by, you retracted your postings, because you were afraid it was unsafe. Actually, a slight crush of the primer is 'safe', but that is a different topic, best discussed in another thread.
Using the o-ring under the primer in either the Western Powders plug, or the CVA plug can stop blow by. The use of the o-ring in the primer seat isn't required. Using the o-ring in either breech plug, is just one way to stop blow by around the primer. The nice thing about using the o-ring, is it can stop blow by without crushing the primer.
One can purchase the o-ring from McMaster-Carr. The o-ring is so inexpensive, i toss them when i clean my rifle after every shooting session, even if i only shoot it once, or twice.
Another possibility, if one wishes to shoot Blackhorn in a CVA rifle, is to modify the standard QRBP. About this, i can furnish more information via PM.

I know exactly what I wrote, there was no misunderstanding. When I first started adjusting for primer crush (Info from a forum) I experienced a few things, after I heard there was an accidental firing due to crushing a primer my recommendations changed to adjust the firing pin bushing according to CVA's recommendations (Which specifically forbids crushing the primer) That is Flush with the breech face. If that would crush the primer a minute amount so be it. I do not recommend anyone to crush a primer. The O-ring is just one more way to crush a primer. I don't know how you got on this subject because all I said was I heard the O-ring will wear out in about 15 shots. I was not afraid crushing a primer was unsafe, I new that crushing a primer was unsafe, unless you discount a muzzleloader accidently firing from crushing a primer. Any other questions or remarks take it up with CVA they are probably more informed than me.
By the way just to be clear, I never mentioned anything about blow by or crushing a primer. You must be on your own trip.

The o-ring is just included as a helpful option, and if used, will reduce blow by. It isn't necessary to use the o-ring. The inclusion of the o-ring, with the breech plug, is like a bonus, and shouldn't be considered a detriment.

Is your statement specific-to the Bloodline bullet only?
I think you may have opened a can of worms here. The reason I'm curious centers around my decision to shoot 50/40s (only) at the range in the spring of 2015.

What is your definition of a light load?..... and with what powder?

Now if you had a 1-20 or even a 1-24 twist, you could probably be just fine with loads under 100gr of T7 or BH209. I have not tested this in my Savage 1-24 but in a 1-20 45 it appears to be the case.
I really doubt a 1-28 would be enough for a 200gr Bloodline without using full power loads of 100gr or more.
