Don't need to try again. Your very first link says:
"shooting 600 today, sling. 6.5 Creedmoor, 41.3 grains of H4350, .010" off (2.790") velocity 2750 fps, 147 ELD with 1/7.5 twist krieger."
you said "The 147's aren't being hotrodded or over twisted. Clearly, you didn't read the linked discussions"
Sounds hotrodding to me. Other post had issues with over twisting and more hotrodding, hence the reloading data. Not to show the difference between structural stability of the bullet when over pressured, but to show everyone that your opinion is one sided, not fact based.
I said, if you want to go outside factory recommendations, do your own testing.
You got butt hurt.
Cry about it.
No one is butt hurt. Get over yourself. I used YOUR words. If you have a problem with that, it is YOUR problem.
Even in a 7.5 twist, there is NO WAY that is enough to cause structural failure of a bullet and 2750 is NOT hotrodding by any definition.
Link #1: 2750 in a 7.5 twist. NOT excessive. Even Hornady hasn't asserted that and THEY would be in a position to know.
Link #2: Three different rifles with 8 twists (Hornady's recommended twist) @ 2880, 2915, and 3061. ALL well within typical 6.5 velocities for the respective cases. Are you really going to assert that the structural integrity of a given bullet is based on the case from which it is fired?
There is ZERO link between chamber pressure and bullet integrity. I defy you to prove otherwise. Your insistence that your assertions are fact based are laughably ignorant.
BTW, I HAVE done my own testing with this bullet, up to mid-2800's from a standard .260 with RL-26, in a Savage 8 twist. Fortunately, no structural failures as yet. My concern is that the problem may be related to specific production lots. Waiting to see how this issue shakes out before buying more 147's. I have a few hundred more of the 147's left, which I will continue to shoot while waiting for answers to the reported problems to emerge. Until then, 143's seem like a reasonable substitute. I know of others using them with good results.
The fact that this problem has also manifested with ELD-M's in other weights and diameters seems to hint at some sort of issue with the jackets. Given that I have personally witnessed jacket failure with early production AMP-jacketed 178 BTHP's, at sedate velocities in a .308, I suspect an issue with the manufacturing process. This is a phenomenon that did not seem to be common with the previous AMAX designs, which were pre-AMP process bullets.
