I am looking for any load info for 300 win mag shooting 200 grn eldx using imr 7977. So far with other powders I’ve been able to get 3/4 inch at 100 yards Ideally I’m looking to get 1/2” and have heard good things about this powder any input is welcome.

Getting exact load info on the ELD-X is challenging but for 200 grain SPBT bullets and IMR 7977 powder the Hodgdon's reloading site has starting and maximum powder weight information. I think you have a theoretical winning combination. IMR 7977 was made for the 300 Win Mag! I would be interested in knowing your final recipe. My brother has a 300 Win Mag so I may mention your combination to him.
