153 gr 8mm Mauser

[Andy]

Shown below between similar commercial bullets is one of the 154 gr FMJ Open Base bullets pulled from the million of rounds of Turkish ammo imported into the US about 15 years ago. You can see the aggressive crimp which was applied. As mentioned, you will not achieve an MV of 2880 fps with a cast bullet without severe leading. However, 2200 fps is achievable in my experience with a gas-checked cast bullet.
