Yes, that is what we could do, and it isn't as difficult as i had it in my mind it was. I think it is a worthwhile first step toward improving the bp.

What i wanted to do originally was make a deeper concavity in the bp, and drill out the flash channel, but then i realized there isn't enough material there to allow the deeper concavity. So i decided to try the vent liner and forgot that one could drill out the flash channel without making a deeper concavity in the end.

I guess i will give it a try on Saturday. Like sabotloader say, when the flash hole wears out, one can proceed to install a vent liner.
