ok, took the gun back to the 'smith. the KDF was put on some time ago, I took it to 'smith long ago and was told there was not a problem. anyway his son is the new 'smith and he checked it over and one of the port holes on the KDF had a burr on the inside. he reamed it out to +.012, assembled and test fired. no indication of any inside contact with the bullet. hope this fixes it. need to load up some and test the groups both with and without the break. I don't hunt with the break on, only target shoot with it.
