Air Venturi Round Ball - High-Quality Air Venturi Ball for Paintball, Airsoft & Outdoor Sports | Perfect for Target Practice, Training & Recreational Shooting

While I understand air venturi is an air gun company I thought I'd use these in my colt 1851. The dimensions are good but most of the balls have a small bit of lead protruding on one side from not being ground off from the casting. The lead is also a little on the soft side even for lead. I've noticed when pressing them into the chamber my loading press deforms the front of the ball. they do infact work for cap and ball and are reasonably accurate at 50 yards but Hornady round balls are half the price. if this is your only source of lead go for it.
