Sure it's cleaner, but I am sick of all the hang fires.... from completely clean CVA accura using fed 209a primer I didn't even get THREE shots off before I had my first hang fire. I'm done with it for good!!
Suit yourself, but you could find out how many many many others use BH209 successfully.
The sabot needs to be a tight fit in your rifle. The bullet needs to be pushed tightly against the powder. The breech plug needs to be 'clean'. This involves using a 7/64" drill to remove the carbon from the flash channel. Normally, the CVA requires a magnum primer for success. Do these things, and BH209 should work for you.
I too have experienced some disappointment using BH209 in my Accura. However, by making my cva breech plug look more like a TC breech plug, i have thus far seen 100% reliability in my Accura using BH209, and this includes shooting it last winter, after it was left out over night in temperatures less than -15*.
badbowbender2 mentions installing a vent liner to improve the cva breech plug, and in my experience it works. Pictured is a cva breech plug with the vent liner installed.
Others suggest enlarging the cva flash hole. My measurements show the cva flash hole to be some larger than the TC flash hole. My Omega(s), and my Triumph, have been 100% reliable using BH209, so, to me, it doesn't seem like the size of the flash hole is the problem with cva breech plug.
Pictured below is a home made breech plug that fits my Accura. It is tested, wrapped with teflon tape, and almost ready to install. If you wish to try it, you need to furnish a vent liner, postage, and your address.
The headspace of this breech plug is about 0.016" less than factory, which will help reduce blow back some. If it is too tight, one just needs sand the end slightly.
