Pre64 300 H&H loads with 200 ELDX

[longgun505]

I searched for data and came up dry so I'm turning to the crowd for a jump off point. I like retro-weapon hunting and have a few old rifles that have rivaled any of my custom bangsticks. I have recently purchased a beautiful specimen pre64 70 in 300 H&H circa 1951, and am in need of pet loads with Horn 200 ELDX's? Brass is another component of this endeavor that's proving difficult. I have data for a lot of different manufacturers weapons, just not the pre 64 70's. Mainly interested in these particular rifles with the usual suspects H4831, IMR4831, R19, R22. Come one, come all! The season is upon us
