Re: winter max loads vs summer max loads??????
I keep my ammo in a cooler... but just to stabalize the temp, not to cool it. I have however packed loaded rounds in ziploc bags and exposed them to various temps (packed in ice, with ice but insulated, air temp, in my pocket, under my clothes against skin...body temp, between ziploc bags with the hottest tap water I could get, and set on the heater at work... 140 something if I recall)before firing them across the chrony, all to test the temp stability of a few different types of powder. You could certanly pack your test rounds in a cooler and head to the range. Makes perfect sense to me. What cartdrige/powder you using? I may have some data for you...
