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.
