I went ye olde local gun store to get 9 mm ammo for practice and to decide which I would need for competition. PMC was relatively cheap and I know it is the same manufacturer of the M2 ball surplus ammo that I use for my beloved SA M1 Garand. I want ammo that is clean firing that will leave the least amount of fouling and have the biggest bang for the buck! What does everyone use for both plinking and IDPSA?
