Hey all. I was at my local gun shop the other day and I noticed a policy sign posted behind the counter essentially saying that shooting Walmart ammo will void any warranty that they provide with the repair of a gun. I asked about it and the guy said that it is because it has been tested and the ammo that companies sell to Walmart is actually of an inferior quality and can thoroughly mess up a weapon. Is there any truth to this? Has anyone heard anything about it?
