It's getting there, Kerry. A vent liner will help considerably with ignition, I'd think - or going in from the inside and coning out the metal right enxt to the vent hole with a rounded diamond bit - Princess Auto had a package of about 12 different shapes- $7.00. I used one for the India Pattern Bess I had. Holding the rounded bit on the inside of the vent(from the breech plug end, made a perfect cone to the vent, leaving about 1/16" wall to the outside.
