I have Spear and Hornady manuals and neither address +p.
The SAAMI standard for 9mm +P is 38500psi compared to 35000 for 9mm.For the most part, I could only find +P 38 special listings. Is there a SAAMI standard for 9mm +P? Even the 38 Super has +P listings in Hogden online data.
That's kind of answering the question not asked isn't it?Its pretty much up to the manufacturer of each gun to deter man if their gun can handle +p ammo. They know how strong their guns are not the bullet mfg. I have Rugers and a Taurus and they either say do or don't use +p ammo. +p is pretty much a waste of money any how. Learn to hit center mass or between the eyes and the question becomes moot.
I was simply wondering to see if we could reproduce the NATO loads. But you and others are correct, one gains little with the +P in the 9mm. Not like the .38spl. +P. I imagine at this point I'll follow Hodgdon, Hornady, Speer and Lee recommendations.Sr40ken, Why you don't see 9mm +P loads in reloading manuals? ...... 9mms have a small case with very minimal free volume when loaded with medium burn rate powders. Just a very slight increase in powder weight can easily drive pressures over the established limits. So ... it becomes a liability for reloading manuals when the difference in a normal load and a +P load can be as little as .1~.2 grains. I know this doesn't answer your question but it is "why".
Thanks AndreSaw this addendum on the accurate website. Small .pdf file. Maybe it will help?
I believe to reproduce NATO performance, you'd need a 115gr bullet going about 1260 FPS. Ken Water's Pet Loads has some loads that achieve this from a 5" Beretta. They are not called out as +P, and he does not use pressure testing equipment.I was simply wondering to see if we could reproduce the NATO loads.
