[QUOTE="J E Custom, post: 1266111, member: 2736"] Probably the reason you haven't had any feed back is because this is an experimental process and it can cause as many problems as improvements. What Little I know about it is that it's supposed to replace extended freebore with partial rifling. Free bore is not an issue if properly sized ammo is used in a true concentric chamber, Plus it helps control Pressure. this system of minimal rifling for part of the free bore Is like having very slight lead angles (Less than 1o) that will cause poor initial engraving on the bullet on high velocity bullets because of starting torque. On less powerful lighter cartridge/bullet combinations like bench rest use, it may work ok, but lead angle is very important to get good engraving on the high velocity, heavy bullets that we use.
