About 100 yds. with an Encore .378 GNR using IMR4064 and a Hornady 270 gr. Spire Point. It was about 100 fps under the hotter 3031 that Sean was using. I think I remember that.
I'll get the load at work for you. Of course you have to work up to it in your gun. I like to seat my bullets a little off the lands to. That affords several grains more internal capacity. Not that I fill it all up but it can afford some pressure level flexibility.
It's just a little down from 3031 in speed but not as hot pressure. Puffy liked 3031 too.
2008 at the Y-O, I was sick as a dog. The Encore .378 did it's job, one shot, no tracking.

Anyone use IMR4064 for 378GNR?

I took a nice Whitetail at the Y-O a few years back.
