    I am converting an 1851 Navy Six to a 38Colt Kisrt Navy. Im new to reloading. My Question is, will a modern 310 tool, setup with the stock 38spl /357 310 dies, make 38 colt ammo? If not what modifacations would/could make it work? I work in a machine shop so i have access to equitment. Thank you for any imput you may have!

    Yes, 38 or 357 dies will work for the Colt except the crimp die. You can either get a crimp die for the Colt cartridge, or machine off the correct difference from the bottom of the 38 crimp die,

    Bernie Rowles at Old West Molds.com can make you a modified Lee Crimper with inserts for 38 Colt, 38 Special and 357 Mag. Same crimper, but the insterts are for the case length differences.

    Hello, Macrus. I have a Kirst .38 long colt conversion cyl. in my 1972 Colt .36 1851 navy revolver. I am able to do all loading steps using std. 7/8-14 dies...except crimping..the .38 long colt case is too short. This is where an original Ideal nickle plated No. 3 dbl. adjustable chamber .38 Spec. tong tool came to the rescue.
    As you know, this and the later 310 tools use no shellholder. Further..the die can be threaded down an unlimited amount...the reason my .38 Spec. marked tool is able to crimp on the shorter case.
    Your 310 tool will work fine with no alterations needed.
    Are you planning on using the heeled or hollow-base bullets? Best of luck!
