I buy or scrounge a roll of those bags you get in the produce section of the grocery store, and put all the meat in that, forcing all the air out of the plastic bag before twisting the top closed, then wrap it up good in freezer paper. We have good results with that on all our moose meat and venison. Game birds go in plastic freezer bags, but they usually get devoured pretty soon after harvest.
Been doing that for years, but we usually eat through a moose in a year, or several deer. Anything left over when the next years game is processed get thawed and made into sausages.
