Weapon Shield Is The Winner In The Gun Oil Wear Tests
FP-10 was the 1st generation formula and is now replaced by Weapon-Shield which is the 5th generation formula.
Under carefully controlled laboratory test conditions, this basic test was performed with a variety of lubricants for a 60 second time period and under a 266.5 lb. roll to ring pressure. The method of measurement devised to wear consisted of measuring the length and width of a “wear mark” (see drawing) and multiplying them together and multiplying by 1,000 to get an index number. This table allow a comparison of index number (higher number indicating more wear) of the various lubricants used in this test.
Weapon Shield (FP-10) has the least Wear Index Number (0.9), Scar Length (0.039”) and Scar Width (0.024”) among 33 competitors. It is concluded that Weapon Shield is the best product.
