Yup, it's me and that 1851 colt conversion. Traded the funky box of remington green to my neighbor. Neighbor had two more boxes of Remington green and they were fine. So anyway I got two boxes of Remington and a box that my neighbor reloaded 225 gr lswc on 6.5 gr unique. All three boxes the leads the bullets rattled loose until they started catching on the barrel. I would then have to push the bullet back to its original position to make the gun function.
