Official Hammer bullets Terminal Performance (picture heavy)

Can you post a picture of it cleaned up?

We do expect the petals to shed. We don't always get exactly what we want, but usually do. The current supply of copper is very consistently shedding to our expectations. We now have about a years worth of copper on hand. No worries about consistency in the future.

That bullet looks like it hit unstable.

My thoughts also

Velocity was

Velocity?

The velocity was 2491fps over a five-shot group, one round hit 2501. I got as high as 2557 fps over a five round spread with no real signs of pressure;; however....my rifle did not like that load at all. I am using totally prepped, new, Hornady brass, Federal LRM primers with the 4350.

Cleaned it up and looked closer today. Looks like only 1 pedal shed. The one i found. Other 2 peeled back as you see in your blown up pic. Its the 155. Out of a 28SM with a mv of 3430

So 28 Sherman mag, 8 twist, 155 either absolute hammer or hammer hunter, which needs an 8.5 or 8.75 twist respectively, muzzle velocity of 3430, impact velocity of 1951 fps, I would think it would be stable at any elevation. Was there any debris or limbs/branches in the way?

Did you all see this one?

Nope wide open country. Entrance hole was tiny. I was happy with the performance now you guys are making me second guess it. 155HH

That look like something from the movie, Tremors. The big worm.

So bottom line means the bullet failed to perform, *as it is intended*.....bullet was stable at impact, and there was no good reason for it to do what it did, HOWEVER....bullet failures happen, with every manufacturer, none of them are immune, so look at the end result.....very effective, very dead animal. No reason to second guess it unless you are wanting something different from external ballistics out of the bullet. Documented performance like that from these bullets is the minority, not the majority, as are bullet failures with many other manufacturers. I would keep note of it, and if another one fails, maybe add more weight to it, but I wouldn't give up on them at this point. When I test badlands, Hammers, bergers, Hornady's, Noslers, or any other bullets, as far as terminal performance, I look at end result. First, (assuming a good hit) how quickly did the animal die, and second, how much meat loss was there. External ballistics is another subject.

 

[Varmint Hunter]

Here's the exit side on a whitetail that was hit at 501yds with a 124H shot from a 6.5PRC at 3,200 fps. It looks like the petals stayed close to the shank and left an impressive exit hole. Surprisingly enough, the deer got about 60 yds before piling up. There was good blood sign starting right from the hit.

The only other possibility could be a damaged meplat from hitting the feed ramp hard or had been dinged up from a drop or something.

Or the stated twist is not what the barrel is marked, I've had two the weren't as fast a what I ordered.
