Ok, now that I have a minute, I will be doing the testing of the 280 grain HAT bullets in wet phonebooks and comparing them to the 300 grain SMK side by side. I will also be doing a ballistic coefficient test as well. It probably looks on schedule for Saturday but I thought I would start the thread tonight. Here's a pic of the test bullets: The bullet on the far right is the bullet seated out a ways to show how long it is. The bottom of the bullet is actually at the body/shoulder junction! The other two on the left are loaded to fit a REM long action magazine. I loaded the 300 grain SMK with 50 grains of N170 and 48 grains are behind the 280's. I loaded them VERY light to simulate a 1200 yard (roughly) impact.
