Two answers that affirm you have a positive view of fire lapping, but both fail to address the question, why fire lap? :hmmmm:This will be a Cast Bullet gun, I always Firelap Cast Bullet guns! Fire lapping done right, is a win, win, it has helped every Marlin I own so far.
As stated above, the manufacturing process of a Marlin can leave tight spots in a barrel, stampings as in logos or writing, proof marks, dove tail cuts, drilled holes, and tooling marks, etc. We all know we need at least .002 over bore size for Cast bullets to shoot accurately, if you have tight spots, the tight spots can affect the diameter of the cast bullet when shot. That causes accuracy issues and leading issues, Firelapping removes those tight spots, smooths the bore, and smooths the throat, Firelapping when done right will help the firearm shoot more accurate with either Jacketed or Cast, will foul less with either Jacketed or Cast and will make clean up far easier and less frequent. Firelapping In a nutshell, is shooting a cast projectile, that is impregnated with lapping compound around 12bhn, at airgun velocities.Two answers that affirm you have a positive view of fire lapping, but both fail to address the question, why fire lap? :hmmmm:
