Having no luck finding data for this bullet in 375H&H.tried working up some loads with 4350 to the 270 grain data.Might have to try a faster powder the 4350 starts to bulge the case at 79 grains.Bullet seated out to 3.6".Nosler site does not list anything on their website..Any help would be gratefully accepted.thanks

Try RL 15 starting at 68 grains and work up toward 71 grains. If it is sloshing around you can use 2-3 grains of Dacron as a filler.

I have been using 72 grains of IMR 4064 in my Ruger No.1H .375 with the 260-grain Accubond. It is pretty accurate, but I have not yet chronographed it. However, it should be in the vicinity of 2700 FPS. I suspect it might be possible to get higher velocities than this with the 260 grain, but 2700 is plenty for my purposes!

Nosler say to use the data from Nosler #4 and #5 for the 260 grain Partition.
