    I fear your hopes have already been dashed Andy. If my suspicions are correct, actual manufacture of 310 stuff has probably been discontinued by Lyman for a while. They’ve just been selling off the leftovers. Go back and look at the shrinking lists of available die sets for the last few years and see whether you agree.

    I don't think you could get the fifteen thousandths or so you'd need to squeeze a 5/8 die down to for it to work. That's quite a bit. To tighten a die, you open the locking screw. The locking screw pushes the die open. Doesn't clamp it shut.

    You are correct, .609/.610 tap.

    I've never looked to see what taking tension off the screw resulted in. I would assume you would have to remove the screw and tighten the die down in the holder.

    You are probably spot on with your analysis, collapsing a die .015 is huge.

    As a novice machinist (whose lathe was made in about 1950 and has pick gears instead of quick change) I have to ask, do most modern lathes have the capability to set up and cut 30 tpi? Of course turning major diameter to .609 would be no problem...

    I’m still wondering about the hardening step. Would it be needed at all for a die that would see moderate use mounted in tools that lack the physical strength to exert a whole lot of pressure. Inquiring but poorly informed minds want to know!

    These are at best neck sizing dies so, no, hardening steel would not be necessary. A good polish, yes, but we are not swaging bullets here.

    30 tpi is no problem for CNC lathes, but most lathes with quick change gearboxes do not have the capability to do 30 tpi. With pick gears, it would be easier to accomplish, though it might require a gear or two that you don't have. I think that it would be very hard to wear out a die made with prehardened 4140 or a modern rifle barrel that has been removed because of accuracy deficit or for a caliber change. Since the greatest force required is for neck sizing, just be sure that that part of the die is very smooth.
    Spell check doesn't work in Chrome, so if something is spelled wrong, it's just a typo that I missed.

    I have a steel set of handles that are marked 30-06. The hole in the handle where the case goes into is way larger than a 30-06 case is.
    The hole measures .560 or so with my calipers. A bit bigger than the .473 I get on a 30-06 case.
    I was thinking, would it be possible for some with a lathe to ream this hole large enough to cut threads the rest of the way through the handle?
    Once the hole was threaded could they could counter sink the hole so you could thread in the adapter die? While doing all this you would need to counter sink the hole for the locking screw of course.
    If so, how much do you think it might cost?
    I have this set of handles in the 310 swap thread, no takers as of yet.

    You need a mill, not a lathe for the job you propose. In fact, with the right vise, you could probably do it on a drill press. Then you need to find a tap for the proprietary thread to hold the adaptor. The only downside is that the little “bumps on the handle opposite the handle still mark and wear more quickly than the later tools with the spring steel “fingers” to take the wear from the pc die’s punch.

    One thing to consider is that the existing 0.560” hole may be bigger than the threads of the factory adaptor and you may have to make custom bushings (adaptors) or sleeve the existing hole to start. I am out of the country right now away from all my reloading stuff so I’m working from memory and speculating as well.

    He's a one man shop. Since Lyman quit making these tools he's not been able to make stuff. He probably doesn't have your items in stock and has to make them. This can take awhile.
    When I ordered the priming chamber and shell adapter for my 7.62x54R set up it took about 3 months to get them.
    Once they got here I was very pleased. The workmanship is faultless.

    44magLeo, I assume you are talking about the 310 shop? When last I was in contact with him I got the impression that he contracts out his machine work, so getting it done in a timely manner becomes more complex by about another order of magnitude.

    At one time one of the benchrest specialty die makers offered blank dies for the 310 Tool... for $50 per blank die!. If I need to get into nonstandard dies (or even ones that have become unavailable) I guess I’ll have to set up to make my own, or alter some older, cheaper dies.

    I have the proprietary size tap for this thread, if you ever need to restore the ID threads in anything, let me know.

    I did some checking a while back, one can have a special die made for this thread, but it is cost prohibitive, $150 - $175 when I last had one quoted.

    Yes Scott, that’s about where I am too. I have a pretty broad assortment of pick gears for threading on the old lathe I mentioned and an instructor from the local Community College has offered to come help set it up for thread cutting. I’m hoping I have or can get the right gear for 30 tpi, so that expensive die won’t be necessary. In the meanwhile, I’ll be on the lookout for odd 310 dies with small diameters to rebore as needed.
