Full Metal Jacket
member
there are very few ammo makers that offer full power 357 magnums nowadays, unfortunately.
They don't list the test barrel lenght though so I assume that's from a six inch barrel.
Magnum ammo hasn't changed, its still the same velocity as it ever was.
Man if you guys want to feel a .357 magnum, load up 125gn jacketed hp's and put 15 grains of Blue Dot behind it. They are very potent, although will show signs of overpressure.
I got the recipe in Hornady's fifth edition. I bought the 7th, and it doesn't recommend using blue dot. But I tell you- it is wonderfully violent.
