Remington Core loct 140s worked best in mine as I recall and actually gave me more velocity than any reload I put together with that bullet weight. I seem to recall they were over 2800 fps in my 15" barrels. I'd also take a look at the Hornady Light Mag line especially the 139 BTSP as they have shot most accurately in EVERY single 7-08 rifle I've owned and that's several. I never tried them in my 15" barrels tho as that was before they were made.
