Okay, in a fit of stupid, I shot my .260 with the on/off brake on with cast. Needless to say I now have the brake leaded up to the point it will not close. Anyone have some ideas on cleaning the lead out? I tried soaking it in Kroil and heating it to about 130 degrees. I don't have a manufacture on it so I honestly don't know how it should come apart. This brake has two sets of holes, one on the inner and one on the outer sleeve that rotates about 1/8 of a turn to align the holes with the holes in the brake. It allows for braked shooting at the bench for reduced recoil, and non-braked while hunting for a little less ear blast.
