    New Casting

    My 2 year old Lyman is extremely sloppy already, maybe 1000 bullets. Plus, I cranked before the lube had heated enough, and pulled the threaded rod right up through the casting. What a piece of junk the new Lyman sizers are. I called Lyman and they wanted $125 for a bare casting. I think the RCBS is a much better unit for wear as the ram is larger and has more surface area. The Saeco is even better. You get what you pay for. I have one of everything but a Star and I'm working on that to replace my worn out 4500 Lyman.

    Better yet call RCBS and they will send you one at no cost. Can't beat that

    I can't believe it's been 6 years since I last replied to this thread! Lyman has some QC issues with regard to their sizers. My older RCBS and Lachmiller units are still working fine. I'm afraid Orange has lost me as a customer for most things.

    I follow the instructions that RCBS has on their website about aligning the sizing die by using the top punch in the hole for the boolit. It works just fine as long as I can find the right top punch so it is the proper size. I also use the flat top nose punch if I can and this also helps with alignment issues.

    I need a small diameter .308 flat top punch. Does anybody know the Lyman or RCBS part number for this?

    Here's a tip: Lymans sizers use a center sleeve that has a concave end. This allows clearance for sprue bulge on bottom of some bullets and seals bullet better at bottom so no excessive lube gets on base of bullet. RCBS sleeves are machined flat.

    Polishing inside sizer with 1200 grit paper will make sizing easier without deforming bullet. You can do this by wraping paper tape and sandpaper around dowel then spin in drill. Not much is needed to get mirror smooth

    After stripping out the set-screw on my Lyman 450 , I read here about the Quick fix, sticky lube to hold punch in place, with a bit of skepticism . But , hey .....it works!
    The punch stays in the socket and aligns itself if the die is not centered.

    Alignment was/is such a concern of mine that I use the Star luber anytime I can, although I have many more sizing dies for the RCBS/Lyman.

    I purchased a Lyman 450 used (a gray color), and had the same issue with alignment. The casting had worn to the point that I can not size anything, the ram has ~ .030 - .050 slop in it front to rear. Side to side is less than .005 slop. I just finished rebuilding it, I used a bronze oil-lite bushing in the casting and machined the ram to fit. I can now size without ruining even the longest 270 boolit. I also added a couple tapped holes in the bottom to hold the "pressure ring" in place, instead of the 15 or 20 prick-punch marks that where there. I just finished repainting the casting and re-blueing the linkage.

    Just ran across this old refurb thread by Keith (thePerfessor) and thought It needed tacked on to keep it from getting lost. Keith, your presence here is missed!

    ^^^^ I wish I had this to start with. ^^^^

    Same process I went through, works out quite well.

    The best advice I can give to you after casting at least 100,000 bullets is,,

    Don't size them , .....rather, hand lube them.
    If a gas check, use the slip on type, not the crimp on.

    If you must size, use an over size,,,,, size die, so it lubes only.

    Seat the gas check with your fingers.

    .
    Best powder for cast bullets in rifles,, 2400.
    .
    Best lead, wheel weights.
    .
    Keep your velocities under 2200 fps in rifles with gas checks.
    Better 1800 fps.
    .
    The best ctgs for cast bullets are: 30/30 Win., 32 Special, 35 Rem , 45/70...
    .
    This is not rocket science.
