IMR 4451

[M70375!]

Has anyone got any experience with IMR 4451 in 375H&H or 416 Rem?

Since it’s discontinued, I wouldn’t bother with an elaborate load work up unless you’ve got a couple jugs of the stuff. If you’re just burning off leftovers, go with whatever is on the Hodgdon site or generated by Quickload. It’s really frustrating when they discontinue a powder right after you’ve dialed in a load.

I just bought 24 pounds of it this spring for $27 a pound , so I am wanting burn some of it up for practice loads in the 375, I just can't get my Model 70 to shoot the 270 grainers that I want to burn up shooting rocks on my morning walks. No room in the mag to play with seating depth, so frustrating that they never made the mag box longer like Remington did.
