Smyth Busters: Will Shooting Jacketed Ammo Clean My Barrel?
This 'Smyth Busters' episode from Brownells Gun Techs debunks the myth that shooting jacketed ammunition can effectively clean lead fouling from a firearm's barrel. While FMJ rounds might remove loose powder and lube residue, they tend to smear lead deeper into the rifling. The video emphasizes that proper lead removal requires dedicated bore solvents, cleaning rods, and manual effort. It also briefly mentions a specific recommendation for AR-15 owners using .22 LR rimfire conversions.
