I have a repop Smith, tried several brass tubes for it and it would never close.
So got to thinking about using my barrel crowning tools..
I have some crown cutters, 90 deg and 11 deg. 3/4" and 1"

They use a brass or steel pilot like this.

On end fits the tool one in the barrel.
Or in this case fits the brass case.
Was thinking if can make it to fit inside the case, give it a few turns and trim the tube to length needed. It would keep the cutting true and good for a gas seal.
May only take 1/2 to one turn then try in the gun.
I will get the spec but I'm thinking it is around 1/8" and the big side to fit the tube would be 516 and 1/2" long with a taper on the very end to make it easy to fit in or bullet head.
Let me know what you think, anyone have a way they trim their tubes other then a belt sander or file.
Other tools have to much set up time and would add to the cost of brass tubes to much.
Also having seen several people at last nationals that did their tubes and still have some fit problems due to not being true on the end.
One guy filed the back side of his, What works best?
Thanks.
