I promised to report back after I got in touch with M. Orlen, and we talked this morning about lengthening the forcing cones on chrome lined barrels. He, at first, didn't understand my concern until I explained my question about whether or not the chrome plating would ever begin to peel after cutting through it in order to lengthen the cones. He explained that when naked steel is chromed it will never peel, if it is cut through or not. He said that car bumpers were not chromed directly to the steel itself, but that there were layers of nickel and copper between the steel and the chrome, thus the peeling you sometimes see with age.
He can't do any .410s for 5 weeks. He has sent his .410 tooling somewhere to be reconditioned, or something, and it won't be back for that long. I told him that would work out great, that I would shoot mine during the early and mid dove seasons and then send it to him to have the cones lengthened. I will also shoot some patterns on paper during that time and send them with the Dickinson, so that he can see what it is doing now, and we can compare the results after the cones are done.
I also questioned him about the .390" bores and he said not to be too concerned about that if the patterns are fairly decent now. The only patterns I have shot with it are on doves, so it will be interesting to see how it looks on paper.
All my best, SRH
