You would be better off than you think. Manufacturing a Zip gun to fire smooth bore is far easier than producing modern primers or modern pressure powders.

Do a google search on "expedient homemade firearms" and you will see what I mean.

And if you do not have the tools or metals to do those kinds of things, the bag of bullets is the least of your concerns. More than likely you are trying to take deer with a long stick that has a rusty kitchen knife tied to the end.

Hold on, I can actually imagine you in that fighting position...
