have been seeing the great consistancy that blackhorn has been having and would like to try some but just want to make sure my gun will shoot it ok?

I know when i was talking to Western about the CVA BP - they indicated that it only had a 3mm flash channel, but they never said and I forgot to ask what size the 'flash hole' was. Do you know?
I think everyone has somewhat settled on .032.

This is going to sound odd, and I am only speaking from personal experiance.
With a 3 mil 'flash channel' and a .029 'flash hole' you may experiance 'hang fires' with BH and the hot primers. It has been my experiance there is just to much primer pressure, gases, and residue to get down the 'flash channel' and out the 'flash hole' without clogging. I believe Western has indicated that a .156" (4mm) 'flash channel' and a .032 flash hole will give the most reliable ignition with the primers they recommend (Fed 209A & CCI-209M)
My Remington has a narrow but short 'flash channel' and a .030 'flash hole' - I do get hang fires with those hot primers. But, if I move back to a Cheddite or STS - it shoots very well. I do clean the 'flash channel' every 12 to 15 shots just to make sure.
Opening the channel with a #21 bit and installation of a Lehigh or Savage vent liner should insure reliable ignition of BH.
I do not know enough about the CVA line to make really informed and accurate comments. The information i have is from Western and they have been/are working with CVA to correct these problem. I have not Western talking about the CVA QR breech plug at all and whether it meets the standards set forth by Western.
I really like the breach plug on the right Its exactly what i want to try. IMO about perfect recess for a variety of loose or pellet powder.
