    got an older TM1 at the Fall Handicap with a fixed choke, with out a bore gauge is there anyway to identify what it is choked?

    If it is factory choke, good bet it will be .038 to .040 With a very hot core.
    They will smoke targets.

    Most TM1 are factory choked Full (or Extra Full), usually there's a marking on the left side of the barrel just in front of the chamber.

    the only mark on the barrel is 18.5 which I believe is the bore measurement, can't put it on paper, since when I got it home found it has a cracked trigger hammer, have one on order from S&W supply, can't shoot it till later this week.

    Above are all right but how many early TM 1's haven't had some one inside the bore/choke. The original ones are getting harder to find. To be sure you need to get it miked some time

    extrapolating the 18.5 bore and my dial venier, it looks like it has a .043 choke, mighty full, I'm thinking of having it bored out to a more moderate IM choke.

    If you do it will hurt resale. I wouldn't go below about
    .033

    as an old man, I am not very worried about resale value,[paid way to much already] I'm more interested in modifying it to a point that I can shoot it , extra full is way to tight, will probably send it to Briley and have it measured and re bored. don't want to spend the extra money to have it bored for choke tubes.
