Default No Vent Liner

Whilst up in the hills today, 5 shots were taken without a vent liner in place. The V2 was loaded with 270g Deep Curl, 110g BH209, green Harvester sabot, and STS primer. The vent liner used for the other 5 shots had a 0.028" flash hole. The chronograph was placed at about 14 yard. Recoil with no vent was noticeably harder. With no vent liner the pressure on the primer was greater, and they mostly leaked soot, and required the use of a leatherman to remove from the breech plug.

The Primers with No Vent liner look cleaner?

I would bet that they are reversed from the velocity chart. We must have been typing at the same time. But what I did notice on the chart is the shots with the vent liner had a more consistant velocity. Difference between high and low is 127 fps without and only 27 fps with.
