Yes Full, but there many variables to this also, all tips are not created equal (materials, densities, and machining). There are irregularities among them. When seated to the metal alloy there is always a finite "gap". This gap is evident when the projectile is in motion and the oil is evacuated. How much oil remains? This is unfortunately not measurable.
We see evidence of this as the "vapor" as most know it, is expelled. I'm unfortunately unable to share which oil is the best and procedures to install yet until I am an active sponsor due to my involvement in this industry.
