I'm doing some chrono tests with a variety of ammo for my new ruger LCR in .357 magnum. I have some older ammo that I wish to test, but I am unsure of the bullet grain weight in the loaded cartridge because I don't have the boxes anymore. I have been unable to find any helpful pictures or info on the web that can tell me what weight the bullets are. I have a .357 Magnum Speer Gold Dot .38 Spl +P Speer Gold Dot that I wish to test. If anyone can help me with some identifying characteristics of the bullet or that can help me ID the actual weight of the bullet that would be very helpful, like weighing your own Speer HP total cartridges in the same caliber so i can compare the overal total weight to mine. Or identifying the bullet weight from my descriptions of the bullets below. Looking at them, The .357 mag has a shallow HP cavity with six tiny triangles of the jacket pointing in towards the center, making the exposed lead appear as an asterisk (*) The .38 Spl +P has a deep cavity to the HP with very little of the jacket wrapping over the rim of the HP into the cavity. Almost unnoticable. Thanks in advance W Wanna kill these ads? We can help!
