    Colt Trooper MkIII with Lyman 358429 358439 length?

    Hello. I just ordered a Trooper MkIII and found a Lyman single cavity 358439 HP mold! The buller was meant to be used with 38 cases because of its length. I did read that some revolvers have long enough cylinders to allow the use of 357 cases. Is the MkIII one of them? Or will I have to use 38s...
