This is the stuff that I use in the bore. To do this RIGHT,it takes about an hour. That includes super cleaning your bbl. IT MUST BE CLEAN for the moly to embed. --- SAWMAN
ADDED:Zoom in and read the jar lid.
I did that some years ago. All equal accept the process. I have lost all my data in the move some years ago but did this to a 22-250,220Swift,243Win,308Win,7mm Rem mag,and even a muzzleloader (it makes them MUCH easier to load and clean).
My accuracy was good,the vels up,and super easy to clean. I also did this to a 30-378Wby Mag and I feel that it saved the throat when burning 115 and 125grs of powder pushing bullets between 3700 and 3950fps. --- SAWMAN
I have always had a velocity decrease when using Moly coated bullets. Its biggest advantage is lowering pressures, but the downside of lower pressure is slower velocity. Adding powder to create the same velocity is why I quit shooting moly coated bullets.
