I should also clarify too. Microlon advertises 150fps increase in velocity over the regular velocity which can range from a handgun at 1500-1700fps to a high velocity round doing 4000fps. Your average mid caliber round probably travels at 2800-3000fps though.
As for the one time treatment; they recommend, from a clean bore, run a patch and shoot 1 round, run another new wet patch and shoot 1 round. Repeat that process 10 times and your barrel should be treated. They also recommend treating friction parts like the slide, bolt race ways etc.
I've had SWAT guys treat their handguns and assault rifles (MP5s) with the alcohol based gun treatment which looks exactly like what they provide to dump into your fuel as an additive and the guns just don't gum up like they did prior to treating them. I definitely noticed a difference in how easy it was to clean the parts that get dirty due to burnt powder. We tell all of our clients that even though the instructions say one time treatment, the only thing that's forever is death and taxes unfortunately so we actually suggest using it as an alcohol based cleaner/re-applicator to ensure the teflon works it's way into the micro pores in the steel. To speed up the process of treating the steel parts we commend using a hair dryer to evaporate the alcohol. Microlon also offers a blue grease and an oiler you have to shake up before use and that stuff doesn't go away. I find very little difference between the evaporated treated to the oil or grease though.
