The test I mentioned was conducted by the Falex Corp., a lubricant testing firm. The American Society of Testing Methods sets specific guidlines for testing products like lubricants.
In the test I mentioned, 30 popular lubricants were tested a number of years ago, by Falex using a F-1599-1A Lubricity Tester. The top three products in this specific test were as follows:
1. Shooter's Choice(MPC) FP-10
2. Tetra Gun Grease
3. Eezox
Obviously this is just one specific test, and should not be used alone to choose a lubricant.
ASTMD-4172 and ASTMD-2266 are popular wear scar tests similar to the one above. The lower the number(wear scar measurement), the better the lubricant performance in this specific test.
Break-Free CLP has a wear scar of .8mm, the max allowable by military spec. MIL-L-63460.
Corrosion X has a wear scar of .58mm.
MILCOMM TW-25B has a wear scar of .42mm
Keep in mind that #1 this is a laboratory test and may not predict real world performance, and #2 it is only one of many tests conducted on lubricants. I have found that several products claiming excellent test results often evaporate quickly, and/or provide very little corrosion protection, as well as a host of other problems. There is no free lunch-one test is still only one test
Four of the best products that I have tested, evaluated, and used in the real world are Break-Free CLP, Corrosion X, Eezox, and FP-10.
