    Little Help with some IDs...

    Hey folks,
    these various dies came to me as part of an estate...
    The black unlabeled die was together with some 243 dies (his main rifle)
    That adjuster part may or may not go with it, the threads do fit.

    Is the 243 trimmer die to be used with a file?

    Then there's a 25-308 resizer and a .257 resizer.

    The Lyman trimmer stuff kinda makes me want to get a trimmer to go with it....

    Any help is appreciated,
    -Jesse

    Yes, the trim die, 1st photo bottom row, is used with a file. You put the shell holder in your press, screw the die in until it touches the holder, then run your brass into the die and file off everything that sticks out until flush with the top of the die. Next, you'll need to chamfer the inside of the case's mouth and around the rim to remove burrs, just one or two turns with a hand tool case reamer.

    The 2nd photo, bottom row, is an old time resizing die. You lubricate the brass, then pound it into the die until the base of the brass is flush with the bottom of the die. The rod is used to tap the brass back out of the die.

    3rd photo, bottom row, I can't make out everything as the photos won't enlarge for me, but the tool standing upright at the right of the two plastic boxes might be a primer pocket cleaner or reamer.

    Up to the top row, photos 1,2, &3 left to right all show Lyman 310-type dies. They should have little numbers stamped on them which would precisely identify them, but very likely .243. The larger things screwed on the ends are actually adapters to allow their use in more modern presses with standard size holes. They're shown upside down, as the outer threads screw into the press with the wide end upward, and then the dies screw into the adapters. That is what they are, adapters, which allow the smaller threads to be used in the larger press holes. The dies may have been made for the Lyman 310 tool, but later Lyman made one of the first bench presses and the 310 dies made to be used in a hand tool, actually a press with handles that looked somewhat like pliers, could be used in the Lyman press. They evolved into very similar looking dies, still with the small diameter and threads, that were made for use in the press.

    Top row, 4 &5, once again not certain, as I can't enlarge the photos enough to read the writing on the dies.

    1st, 2nd, 3rd pic is a 310 bullet sizing die with push rod, it has a thread adapter on it, but backwards. Die in the back looks like a 310 neck size die.

    4 and 5 are a case checker die, to check if the case is resized completely.

    6th is a RCBS file trim die.

    7th is what the box says, A Lyman knock out full length size die. Lube a case and put it in the die then close it in a vise to fully seat the case, knock out with the rod. It's the old way of doing things in a day before real reloading presses were around.

    8th is spare parts for a Lyman lathe type case trimmer.
