I did the same thing with my custom 284 win. I was doing loads with R-17 and R-26. Somehow I did it I placed a starting charge of what I though was R-26. Can't remember right now but it was loaded 2 grains over what I believed was the max charge for the 185 gr RDF's I was loading. I custom throated a McGowen Precision 28" barrel. The rounds at .0015 off lands were approx 3.493" . Any hoot first round out of the ladder fired and nothing unusual until I looked at the Chrono 2,934 fps. Talk about a heavy bolt. I had to wack the bolt handle to get it to bring the bolt up to pull it back the same. When the bolt came out of battery the bottom of the case was so expanded the casing would not come off the bolt face. I extracted the bolt from the action and had to physically pry the case out of the bolt face. I disassemble and inspected the bolt and lugs. It was a REM 700 long action. Scarry event for me. So now I never place more than one powder on the work bench.
