I Gun Juice my barrels for longevity, and Gun Juice will raise POI at 100 yards significantly. I had to change out the front sight for a taller one on a 38-55 Marlin after Gun Juicing the barrel. The POI at 100 yards went up 12 ". Typical change in POI after Gun Juicing is on the order of 3" to 6" rise, depending on rifle and caliber. I have personally detected no increase in accuracy with Gun Juice. Others say differently.
