I have just built a .300 Winchester Magnum and am looking for a load that has worked well for others using the Hornady ELD-X bullet. I have purchased 200, 220 grain Hornady ELD-X bullets. I have found several loads for it but don't know how fast that heavy of a bullet should run. I was hoping Hornady would load a factory round for the .300 Winchester Magnum to try and match their velocity but Hornady only loads the 200 grain ELD-X running at about 2850 fps. So any information would be helpful however I don't need to know what loads work well in a .300 WSM, .300 RUM, .300 Weatherby. These are all good calibers however they will help me in no way.
