I found in my .338 that I was able to use the same load with the X-bullet as I was with the Partition. Start a little lower and work up - reduce by 5% or so, load 5, go up a little, load 5 more, until you reach the standard load or close to max. Start at the bottom, shoot and examine the brass and note how easy/hard the bolt lifts. My .338 shoot the X-bullets very well.
