Shot the 147 ELD-M in my .260 AI today.
Didn't have the best conditions, wind from 5 to 15 mph and about 15 degrees, but by timing my shots with the wind, I got some useable data.
This was a load work up for seating depth, and they do seem somewhat picky on the depth, though all loads shot under MOA. All loads were with 47.5 grains H-4831SC, and I had no pressure signs whatsoever. I shot 2 three shot groups of each seating depth, and adjusted up 1 MOA between groups, as to give two separate groups. As you can see with the .090" off groups, I'm glad I did this, as my first group was the best of the bunch, but this seems to be an anomaly. Judging by consistency, I'm going to say .050" off, or 2.865" OAL is where it is going to give me the best performance. Next, I'm going to do a charge work up over the chrono and see where I find the best accuracy/lowest SD, as well as max pressure. I'll update my findings there, but these bullets are looking promising.
I fired a group above the top left target with my current load with 140 Bergers, to compare to these. That load consistently shoots .3" every time I put it on paper, so that is what I'm shooting for with these 147 pills. If they will do that at 2900 fps or better, I will switch to the 147's.
