RHINO EDM PROGRESSIVE PORTING:

*After 120 days of testing all sizes, shapes and designs of holes (ports), our  computerized design outperforms all other porting available.  *This is accomplished with LESS WAD SHEER due to 1.5 degree of entry of our ports.   These ports have virtually no leading edge to cut or shear the wads, which produces the  large amount  of plastic buildup in the holes and on the barrel.  When the wad has been cut by porting, the shot has less protection from deformation in the choke area.  Our design of ELONGATED ports, not at a 90 degree, creates no plastic buildup in these holes. 

*The new EDM PROGRESSIVE PORTING has a total of 26 holes per barrel, 13 holes per side, and works on the concept of manifold porting.  High pressure is allowing an equal disbursement of air pressure (gases) through these ports creating an acquisition, making it easier to pick up your next target or get that second shot at a bird.  We feel this is the best porting you have ever experienced!

All that is necessary for a maximum performance in a shotgun is a good forcing cone, porting, and a good choke.
