If the 1 primer is not appropriate for the. 40 S&W, just how can it be appropriate for the 9mm, 9mm +P and. 38 Super, which have the sameor even greater pressure limitations?

I assumed the 1 guides were "basic" guides, and the 5 primers were "magnum" primers, because that is just how they are detailed in many primer charts.

008 to 0. 009 inch less. A number of handloaders found this out when one of the "mega-magnum" pistol cartridges appeared a couple of years back. Initial instances were created for Large Gun guides. Some reloaders decided to change to Large Rifle primers to much better manage the high pressures, and they found the rifle primers stood pleased with the instance head, an undesirable situation in a high-recoil revolver cartridge.

Examinations to contrast the results of primer alternative have been published for years. I've been a guinea pig long sufficient to recognize that roadway is laden with potholes. We listened to a variety of requests to include a guide graph in the Speer guidebooks I composed revealing what the numerous guide makers call their guide kinds.



Why? Initially, changing guide brand names from what we utilized in the guidebook might produce an unsafe condition. Second is accuracy of information. One of the last Speer guidebooks before I took control of published a wonderful chart of primer sizes as well as manufacturers' numbers. Almost before the very first printing was sold out, one business entirely transformed its numbering system, and also an international brand name listed came to be inaccessible.

As for the "which is hotter/colder" discussion, a similar problem exists: guide spec adjustment.

I had to take a various view, one based on real-world concerns. We evaluated lots at both optimum normal pressures and at the beginning loads (some labs calculate start lots we shot them). Criterion guides triggered no ignition concerns at limit tons yet posted higher severe variants in pressure and also velocity in the lower stress regimes of the start tons.

Coming to CCI/Speer in 1987, I learnt the actual tale. The metal mugs were neither more challenging neither softer than any other brand name.
