I've been using Ballistol for about four years now, with no complaints. What prompted me to seek out this product was it's use in the gunshops in Switzerland, which I was fortunate to observe during a visit. I figured if the Swissused it, it had to have some merit.
So far my main use for Ballistol has been to negate corrosive primer residue, which I've found when used full strength, seems to work just fine. And while the missus isn't fond of the odor, it goes over better than that from Shooter's Choice MC-7. Use of the latter usually ends up with an invitation to sleep in the yard. I still use the Shooter's Choice for copper fouling.
