Paint diameter varies .006 -.012 for very high quality paint. Field paint diameter can vary from .018" - .040 " Since, the Freak System sleeves and most other barrel bores that are available change by .001 increments and range totally within .008" in bore diameter, the fact that ALL paint will vary in diameter at least .006" or more kind of nullifies any discussion or argument about 'matching paint diameter to a particular bore size'. The context of those 'bore match'discussions are usually focusing on the "Quest for Accuracy Topic" anyway. And since paint is under bore size (just for that reason) it strangely shoots out any barrel just fine or nobody would be buying their paint. Any paint made tends to shoot out of most any barrel made. Sure some shoots better than others depending of paint and barrel and temperature. The "Quest for Accuracy Topic" should be how ROUND a ball is and NOT what diameter it is. The diameter varies widely depending where you measure the ball. Put one in your barrel with the seam touching the walls of the barrel and hold it up to the light. See the gaps? Now take that same ball and turn it so the seam goes front to back. Hold it up again. See the DIFFERENT SIZE GAPS? They are footballs not round balls. Get the round paint if you are interested in accuracy. The undersized ball deforms when it is accelerated down the barrel. The front wants to stay still (inertia) while the back is accelerated. The ball develops a flattened donut shape and the diameter of the ball increases and makes a very good seal in the barrel. Now if that donut flattens too much, it comes out the barrel with a donut hole in it. It breaks the shell and you have a 'barrel break'. Temperature, operating pressures, shell thickness, ball diameter, barrel diameter, velocity settings, etc. etc. can all play into whether or not you have a set up that makes the shell deforms too much and breaks paint in the barrel. For that, the sleeves with different bores sizes would be favored over a short insert or variable bore of 1" in length. Now the BIG DEAL in paint and barrel bore match is limited largely to autocockers is because the detent in Behind the ball in the ready to fire position. If the ball is TOO much undersize, it just rolls down and out the barrel. A real PAIN for the cocker owner. That is were the sleeves, inserts and variable bore gizmos benefit the cocker owner. Just to make sure the ball stays stuck in the breech when you point the barrel down. So I hope you've got a little more information so you can make the right choice for you. If you have a barrel that is working for you, no need to run out and buy another one or compromise saving up for what you want. That Sandridge will out shoot you regardless. You are going to love it..... Congrats...
