Without knowing what other loads you tried, I can only toss out a couple that seem to work in most Grendels.
Since 900 yards was mentioned, I suggest trying 123 Amax/SST over 28.0 grains of 8208XBR. That is one I hear shooting as much as any other. Another possibility is approx 31 grains of CFE223 under the same pills.
If it won't shoot either of those, I suggest going to plan B, because your setup is more than likely in need of tweaking (upper receiver squaring, optics, etc.)
