That's the plan. I'm putting it on the schedule for next summer, and probably with more than one cartridge.
One thing I found in a previous test was that ammo stored in those translucent plastic boxes REALLY heats up in the sun, due to the greenhouse effect. I was finalizing some loads for a double .450/.400 3" a few years ago, and found that my oh-so-carefully regulated handloads did NOT regulate so well after being left in the sun for a few minutes inside the translucent-gray box, even on a 75-degree day. And this was ammo loaded with one of the best-known "temperature-insensitive" powders.
So yeah, I think a feature article for HANDLOADER is in order.
