I am loading 30-06 for the first time, and using the ELD-X 178 gr bullet and Reloader 19. I have the Hornady 9th edition book which does not list the ELD-X, so I confirmed with Hornady on the phone that the COL for the ELD-X 178 in 30-06 is 3.220”. However, measuring some factory loaded rounds, I get about 3.240” to 3.250”. Per Nosler’s load data for 175-180 gr bullets, the starting charge weight is 56.0 gr (2576 fps) with a max of 60.0 gr (2742 fps), with the max being the most accurate. Alliant only shows 59 gr. for a Speer 180 gr SP (2640 fps). And, Hornady starts at 51.1 gr (2300 fps) with a max 59.6 gr (2700 fps). So I think I will use a COL of 3.240” with a starting charge weight of 56.0 gr. Does this sound reasonable? FYI – I wanted to first try using H4350 or IMR 4350, but neither was available. So I am starting with RL19.
