Do you remember where is was throwing the brass?
About 2-5 feet and a little to the front. Not too unusual. It's gotta be too much pressure because it only did it on the book max load. Last week I fired four at 27.4 grains and no issues but I was using nickel once fired brass from Winchester Razorback rounds. The primers didn't seat as deep as I like so I switched to Remington brass. I suspect the nickel cases are slicker and a bit more rigid so they ejected easier but not certain of that.
