Anyone have any good tips for taking accurate ammo temps? I've made several attempts at taking consistent ammo temps: acclimate ammo and temp gauge, not in direct sunlight or wind, and with a laser thermometer. However I get very different readings from minute to minute that are +/- 10 degrees from ambient taken with a Kestrel. So far I suspect that even a little wind on the ammo makes a big difference, the reflectivity of the brass is messing up the readings, and/or I need a better laser thermometer. I've considered using the temp from the ammo box or the plastic holder that the ammo is stored in but wonder if the higher heat transfer of the brass actually makes the ammo temp vary more than the plastic or cardboard packaging. So far plotting a X-Y scatter plot doesn't show a good trend line for my measurements.
