I shoot the 180 eldm out of my 280aiI have shot that bullet out of 7 customs and 3 factory rifles. In calibers ranging from 280 ackley to 28 Nosler. The 175 eldx could be the most inconsistent bullet on the planet. Factory guns struggle to shoot under an inch, and only two of the customs shot them under 1/2 inch. Even with the customs there is always a flyer. All of these ten guns will shoot Bergers, Sierra match kings, and Nosler accubonds sub-1/2 inch. If you weight sort a box of 100 eldx's you will usually have 7-9 different weights. Then if you measure ogive to base you'll get 5-6 more groups of bullets. I called Hornady on both the 175 eldx and the 180 eldm. Their tech said they were designed for 2800 fps. That being said they didn't shot well out of two 280 ackley's at 2850.
2900fps and .13 inch group. They are awesome
