Loaded up 15 rounds with the new 180 ELD-m in my 28 Nolser last weekend. Got home in time to run out and give them a run out to 650 yards. I shot one at 100 just to see if POI was close to the 195 Berger I was sighted in with. Elevation was perfect and windage was slightly left of center so that's close enough to accomplish my goal. Next I shot a group at 350 on paper and they shot into basically a 1 inch group. I then shot 3 at 600 dialing based of the G7 BC Hornady published first shot went low came up .1 Mil and next was dead center. Then things got interesting. Next shot nada.... except I saw dust blowing to the right about 300 yards down range? There is a crown in the ground at about that 300-350 but I found it hard to believe that the arc of the bullet wouldn't have easily cleared that even if I shot way low. I thought maybe I just missed the plate due to a wind gust. So now I go to 650 first shot was .2 Mil low and so I let the barrel cool then fire again this time I see the dust again in the scope and no bullet impact So now I pull out a 195 Berger smack the bullseye first shot at 650.... this indicated to me the wind did not blow me off those two shots that vanished. I have never had a bullet disintegrate in flight but now I am thinking that is what happened. Velocity was averaging around 3265fps

Wouldn't think there is enough speed/rpm to cause the bullet to fall apart.

Only weeks ago I saw bullets coming apart out of a 6 mm with I think a 1:7 if memory serves. Every time the jacket came off one, I'd see a puff in the air 40 to 70 yards in front of the rifle. It sounded different too.
And on a cold barrel it tended to not happen. Once the barrel was shooting it's third, or more shots, it was making the jacket come off.

I said when I got the rifle if the 195 shot good I was not going to waste barrel life tinkering. So now I guess I will just stay with the Berger load and be happy... although there is the new Sierra 197 MK?

Had a cooler barrel then too. That could be the case. I shot 4 long spaced shots with no issues. Barrel was very hot. So I laid it aside and pulled the 6BR and shot it. Then I pulled the 28 back out fired 3 shots spaced about 3 minutes apart at 600 yds and the 3rd vanished. The next one that vanished was also a hot barrel 2nd or 3rd shot

Idk. Seems to me like something else is going on. I've only seen bullets come apart when moving/spinning very fast. Maybe you got a bad batch with really thin jackets.

What's your twist rate of the 28 Nosler barrel, David?

Yes, over-spun is the main culpret. I was just saying that I've seen over-spun bullets stay together the firsr couple of rounds, then poof, once the barrel heats up. DStroud, what's your twist? If it's a 1:8, I'd expect 180's to be fine. And agree with dee, it makes me wonder if there's a bullet jacket error from the manufacturer.

If you have an 8.5" twist barrel (to stabilize the 195 Berger) and pushing the 180 grain ELD-M at 3265 fps, your RPM's are 276,000. In an 8" twist (which is what mine is), you are at almost 294,000 RPM's. That's A LOT of spinning and centrifugal force. Hornady runs a normal jacket thickness on their match bullets, so it's not beefed up like the Berger's are.
Take a typical 300 WM with a 190 grain at 3000 fps in a 10" twist, that's running at 216,000 RPM's. Take a 308 Win with a 168 bullet at 2700 fps in an 11" twist, and it's only running 176,000 RPM's.
So, that 180 ELD-M is spinning it's A$$ off!

What's your twist rate of the 28 Nosler barrel, David? 1/8 twist The first bullet that I was not sure what happened was traveling 3265 but the next one that disappeared was 3308fps as I tried multiple charges

Hornady recommends a fast twist to run them. I'd call and ask them what their thoughts are.
