Never understood "dirty". You have to clean the pistol anyway. If it's dirty enough to start jamming, just clean it sooner. We shoot ammunition like WW white box because it's cheap, not because it is super clean or accurate.
Is the Walmart Winchester white box ammo different than the Winchester white box ammo that I purchased at the hardware store? Because I am not finding it to be dirt and it is very accurate out of my Sig P320 & P365
