heavy 9mm bullets
« on: September 12, 2006, 09:10:59 AM »
I've noticed some refer to the 147 gr bullets...
if it works for thiem in this pistol, great...ammo choice
depends on what a person feels good with and what the gun uses well...BUT, the 147 or other bullets above about 124 gr
for 9mm are not the best service use selection...and probably not for a gun as light as the R9.
might check these out...most effective appears to be the good old 115.

Keeping in mind the Rohrbaugh is actualy a calibre un to itself, ( No +P or +P+ ammo) in standard 9mm X 19 (Luger/parabellum) only, I have opted for the heavy bullet. If these keyhole on me so much the better as the 147 grain has more length to tumble than others. The original 9mm X19 load was a straightend .30 Luger case with .38 cal ( 355) bullet,  designed to operate at a MAX ( read red line) C.U.P. of 40,000! Today, +P+ and "NATO" rounds often have this level of presure but im sure you already know that, along with European 9mm ammo is almost always loaded hotter as well.

Here in the states, the .45 a.c.p.  has traditionaly been the "meat and potatoes" handgun load ( in auto form) and as such, 9mm ammo here has always taken a back seat to research, development, etc. Most "standard" 9mm ammo is at peak pressures of 33,000 C.U.P. with the "Hot new" .40 S&W and .357 Sigs generating upwards of 37,000 C.U.P.  

What all this means is basicaly if the R-9 were able to withstand such higher pressure extremes you'd probably see models offered in these two calibres. This seems to be the reason behind the latest "whopla" over the .45 G.A.P. project. Yes the .45 A.C.P. operates at very low pressures and as such a .45 G.A.P. is certainly possible due to the similarity in operating pressures, coupled with a shorter over all length more condusive to being stuffed in a 9mm size frame, But ill lay odds the .380s will make an appearence first.

interesting...I may give the big bullets a try...I'm still looking for something that works in the pistol well..and maybe in this
little lightweight the big bullet is the best way to go....
mushrooming fully, etc are probably non-starters with this pistol anyway.

one of the best discussions I have found on the rohrbaugh and bullets is on the Seecamp forum under
"other guns".
