I've been using the 147 eld for a few years in 6.5 addiction, 6.5 creedmoor, and 6.5x47. The first 2k box and all the 100 count boxes were basically interchangeable. However, this last 2k box was a different bearing surface length and to get the same jump has to be seated .015 deeper. That and the increased bearing surface caused a lot of load rework. I had shot Berger or JLK for 10-15 years years before that in all my match ammo and went to the eldm to save money. However, I never had to rework all my loads with the Bergers.
The 147s and 123s that I have used have been accurate at all distances, so I have no complaints there. I will add that the BC that is advertised is higher than I've seen from any of my rifles. I usually have to turn the form factor up to between 1.05 and 1.10 to get it to match or come close to my drops.
My son has dropped 4 or 5 deer with eldms. They didn't have time to complain.
I am moving away from the eld for my match loads just because of the consistency. However, for the price I will continue to shoot them for practice or in rifles I don't want to bother with multiple loads for, ie a match load, a hunting load, and a practice load.
