Sorry for the error. Mind was working but the fingers were not.

I went and took all the samples back to metal. Since we know that an untreated sample will rust the worst, there is no use in repeating that. After I got them cleaned, without looking I picked each piece for a test.

#1 = Bore Butter
#2 = Montana X-treme Bore Conditioner
#3 = Birchwood Casey Sheath
#4 = Rem Oil

We will see if the same results happen. Also I paid special care to treating and handling of the test pieces. So in a week I will take a look at them..
