7mm 150 gr E-Tip Report

I tested some 7mm 150 gr E-Tip bullets in my 280 AI. The test consisted of shooting into 1 gallon milk jugs filled with water at 100 yds. Bullets were recovered sticking out the back side of jug #6. Average velocity was 2940 fps. Recovered weight was 148.4 grs for all three bullets and the expanded diameter is 0.587".
Accuracy was just under 1 inch but I will work with the COL to fine tune. I did try one load that went 2976 fps.

Thanks for the report JD338. I have been curious about these bullets but haven't got a chance to test them yet.

Tell me, the two jugs on either side of the jug that contained the bullet look like they are full. Is this just an optical illusion? What side of the pic was the bullet coming from?

Another test that would even interest me more is if you could load the bullets down to a MV of say 2000 fps and retest. This would show a longer range impact velocity and that is what really concerns me about these bullets.

The bullet was traveling from right to left.
The jugs to the right were destroyed and were replaced when I realized I had my camera in the truck! I recovered three bullets, all were sticking out the back of jug #6. I am going to test them at a lower velocity but was more interested in higher velocity and accuracy since I only loaded 10 rounds. More testing to do and I will post my findings.

I also have some 338 250 gr AB's to test as soon as I get them, should be July.

Thanks for the report and info. That was pretty awesome. The mushroomed bullet looks alot like the TSX. I am going to have to try some in my 7mmRM. Good photo also. You should sell it to Nosler for marketing. JohnnyK.
