From Hornady tech support:
At this time we are using the data from our 9th ed. Loading manual for the 175 gr. Wt. bullets. H 1000 start is 53.8 gr. To a max of 60.4 gr. This would be with the ELD-X 175 gr.
Has anyone tried RL-33 behind these 175 gr pills in their 7 RM yet? I've been considering giving it a go.
