Ring load

For this reason, the ringed load does far more damage In many cases than a conventional rifled slug. 

The explosive nature of their construction as well as the accuracy and performance of the ringed load makes this a good choice for defensive use. They should be one hell of a manstopper, and certainly... 

Some time ago. In preparing an article for one of the more conventional gun magazines, I ran extensive tests comparing the accuracy and performance of the ringed loads and regular factory rifled slug 1oad ... 

The biggest plus I found for the ringed load was that they shoot much flatter than the riHed slug. The greatest difference occured when both types of projectiles were fired through full choked barrels of standard 28" length. 

In addition, the ringed loads showed considerably less lateral dispersion. Test groups were ft red from a bench rest at 25, 50, and...

Fig. 8.49 is another schematic representation, published by one of the manufacturers (CPM), showing the typical design of a pellet mill with cylindrical die and two internal press rollers. The execution suggested by Fig. 6.4b.5 (Chapter 6), 8.40, and 8.41 with one press roller is only used in laboratory and small production machines. For structural and process reasons, the perforated concave die can not be very wide (Fig. 8.50). Therefore, to increase the capacity of a given press and more uniformly distribute the forces acting on the ring, up to three rollers (see below. Fig. 8.52) are installed. With two rollers (Fig. 8.49) the capacity of a machine doubles as compared with a single roll pellet mill and triples with three rollers from a ring loading point of view, the latter also results in the best distribution of the pressing forces.

Pilot vent is either vent to atmosphere or to the PRV outlet line. Pilot valve in actual is similar to a ring-loaded PRV. If hs backpressure varies, a bellow type pilot valve should be used.
