9 mm Luger JHP
 

I have bought 50 rounds 9 mm Luger, with JHP bullet, PRVI PARTIZAN U�½ICE from Serbia. Bullet weight is 9,5 g (147 gr), and vellocity is 300 m/s.

Hi:

It's not the shape of the bullet that has caught my initial concern, its the weight of the bullet.

The mechanical system of the pistol was designed for a 123 grain projectile.

Lighter bullets will work with a slightly heavier powder charge.

Some heavier projectiles will also work. I've fired 130 grain bullets with success with a slightly reduced charge.

The 147 grain sounds like it may give you some feeding problems because the springs were not originally timed for such a heavy bullet. You won't know until you fire them. The pistol may function, but it will depend upon the powder charge.

Also, the length of the cartridges and the shape of the bullets may cause jams.

The Luger is a demanding pistol. If the least little thing isn't right, it will jam. When everything is in order, it can be fantastically reliable.

Good luck!!

Pressure curves have absolutely nothing to do with the functioning. (We worry about pressure curves with a blow back action, not a recoil operated action such as the Luger.) The parameter of interest is impulse. A 147 grain bullet at 300 m/s has an impulse equal to that of a 124 grain bullet at 1167 ft/s, The famous Winchester white box load we all know and love drives a 124 grain bullet at 1140 fp/s so it's not unreasonable. The 147 grain loading has enjoyed some limited popularity here in the US.

The problem will be feeding. Forget the ramp and consider the magazine. If the edge of the hollow in the bullet drags on the front wall of the magazine there will be problems. Once on the ramp the edge may hang on the upper side of the chamber but it's more common for lead bullets to cause a problem here.

You have wright, thanks for informations, but I will try. I will send shooting report with pictures. I will shoot from my byf 42, with 6 " barrel.
Nikola!
