I shoot 30 - 1 ratio lead bullets in my .45/70. The man I bought my Browning 1885 Rifle from admitted he cleaned it from the muzzle. I have been told that shooting a jacketed bullet in the Rifle will take out any lead buildup and possibly remove any burrs from the muzzle. I do not have any Rifle bullets, but do have some jacketed .45 240 gr. Pistol bullets. Would shooting a Pistol load with these bullets accomplish anything ?.
