Re: So, exactly how temperature sensitive is Re-15?
Thanks guys!
But, it wasn't actually an oven, just a small cooler insulated further with foam, with a heating pad inside of it.
Here is my test method (copied from another thread):

The way the tests works is that you soak 3 batches of ammo at hot, cold and ambient temperature for at least two hours (5 rounds of each). I use a cooler with a heating pad for hot, the freezer in the clubhouse for cold (an icebox works too), and just sit the rounds out in the open for ambient. Temperature is measured with thermocouples and/or mercury thermometers.
You then fire them one round at a time in a round robin sequence (ambient, hot, cold, ambient, hot, cold...). You let the barrel cool in between each shot. When you fire each round, you just transfer that round from the hot/room/cold storage to the chamber and fire it through the chrono as quickly as possible. You don't want to give the rounds any time to change temperature internally due to contact with the chamber. I set the scope on the lowest magnification and just make sure I'm sending the round through the sweet spot of the chrono (no groups here). You basically want to the Jerry Miculek of loading a boltgun and firing it through the chrono. This is best done on a short pistol range, close to the berm.
It isn't a difficult test to run. However, if you don't have the ability to measure pressure (I do), I would advise putting the heating pad on a lower setting. </div></div>
This is a REALLY easy test to run, and I wish more people would take the time to do it. It's only costing you 15 rounds or ammo and about half an hour of your time. It saves you having to wait for seasons to test the temperature stability of a load.
