9mm 147 grain +P+ load data
- Thread starter summer44

Vhitavouri 3N38 at standard pressure FTW!
This was off a Mossberg forums....ill snd you the link also.
I have just the thing for you. I load 147-gr XTPs over 7.0-gr of Accurate #7 and WSP primers and my chrono showed 1150-fps with no overpressure signs. I shot them thru a stock GLOCK34. I didn't shoot just a few. I've shot a lot of 'em. It's a regular load of mine.
Several guys on Glocktalk were interested in the load (gwalchmai for one) and he replicated it with ease.

FWIW, 7.0 grains of #7 and a 147-gr XTP at 1.100" is just 0.3-grains over MAX from the Hornady Manual and it is UNDER the MAX in Lyman #42 for #7 and a Speer 147-TMJ which they MAX at 7.2-grains.
And this load from my GLOCK34 has absolutely zero flash signature in the dark, proven by time exposure photography. It's a helluva load. Easily gets 1150. Pictures of the flash signature in the glocktalk post #36 link.

I haven't gotten up the nerve to try this with Berrys despite their claims of jacketed bullet load interchangability. Do you have a source of lower priced 147 jhp?
First of all, there's no SAAMI spec for +P+. Second, even +P+ pressures as loaded by Winchester and others can exceed SAAMI max pressures by 25% or more.
Pressures will be affected by a particular lot of powder's burn rate, the particular bullet you're using, brass brand & length, crimp, and your loading technique. Without a pressure gauge, you're in the dark as to what actual pressures are.
Do you really want to chance it?
The manual that came with my Ruger firearms says it's rated for plus P ammunition so I think I feel safe in the + p range, I've been handloading for well over 30 years I know to work up and look for signs of pressure. I would not just load the Max from the beginning. That's why I asked for published data
I may have some in a book. Going to the shop.
