If you're talking about doing it for transport while getting home after a hunt, it would be easiest just to putit in ice chests with regular ice for a couple days drive to get home. Otherwise, if you're talking about freezing it that way for transport it's not really the correct way to do it. The meat should be frozen before placing it in the containers and then using dry ice on the top to keep it frozen on the way home. Meat done that way should only take five pounds or less of dry ice for 2 to 3 days traveling, which is not that expensive compared to taking chances using the other method.
