I have been shooting my original 73 Winchester at CAS matches for 20 years and in the past 7 years I noticed that I was getting a lot of lead buildup in the chamber all along the length of the brass. By the end of a match it would net tight when chambering a round. I would have to take the whole gun apart and scrape out the lead flakes with a dental tool. Several months ago I bought a new Taylor's / Uberti 73 also in 38/40 so that I could stop shooting a gun that was made in 1885. I have shot the new rifle in 2 monthly matches and found that it too was doing the same thing. in fact It had more lead in it. I created a tool with a brass case a brass jag and casting resin to get the lead out, I works well but I am trying to figure out why this is happening in the first place. I have been using the same loading specs for 20 years,
