Thread: Old Lyman moulds

  1. #1

    Old Lyman moulds

    A friend called me a couple of days ago saying that a LGS had on sale a few moulds theyŽve received from an old customer that does nŽt cast anymore.

    I went there and after some bargaining I ended up buying 3 Lyman moulds plus a Lyman lead dipper, all for 70 bucks.

    Moulds are Lyman #452374 (1c), # 358477(2c) and #358242 (2c).

    They are all well used but OK except for #358242 which is somewhat worn from a previous owner smacking it with a steel hammer instead of using a wooden mallet , but the cavities are OK and I hope it will cast just fine.

    I have to admit that I bought #358242 believing it was designed for .38 but now I realize it is intended for 9mm.

    Will it work for .38 spl anyway? I will also like to try #452374 in .45 Colt. The one I have is the old version of this mould, not the newer with a different (longer) shape. Will it work in .45colt?

    Thanks,

    Argie.

    That 358242 at 95 gr. seems kind of light for any purpose in a 38 spl. Of course, it could work but I can't think of a good use for a boolit that light in a 38. I suppose if you loaded them to +p pressures for max velocity, it might make a self-defense load, but I would personally prefer something of 150 gr or better for that purpose. BTW, I can't read the mold number on the top box; too light.

    I thought the 358242 was a 121 ish Gr mold. The 452374 should work good in a 45 colt, I have the ole ideal mold and I believe it cast out at .455 with mold ingredients.

    That 452374 will work just fine in the .45 Colt with Unique or 231/HP38.

    In the late 70s it was my boolit of choice when I shot IPSC with my 25-5. It speed loaded perfectly.

    I have two 4 cav. versions now (late 70's production).

    358242 had two weights. One was 95 grains for the 380 the other 121 for 9mm. It will be a fine shooter but the 358477 should do better with a load of Unique in 38. I am not sure if that is available in Sudamerica or not.

    Thank you all for your answers.

    The one I bought is the heavier version of # 358242

    I have both Unique and ww231 (HP38) so IŽll give it a try with both of them, specially with ww231.

    Good to know that #452374 will work in the .45 Colt since IŽll be using it mostly for that caliber.

    Thanks,

    Argie.

    In the .45 Colt I seated the 452374 slightly past the ogive & put a light crimp over the ogive. You may need to experiment with how far past the ogive.

    I also use the 452374 in my Ruger BH for 50 yard IHMSA chickens.......it's surprisingly accurate.

    I have a Lyman 2 cavity #358242 I purchased back in the 60's for a 9mm. It's a round nose 120? grain and it shot very well. It also worked well in a 38 Special.

    I have used the 121 grain 358242 in 38 special with excellent results. In recent years Lyman changed the 358242 to 356242. I'm not sure whether this new designation also reduced bullet diameter also.

    Is your 358477 the square or rounded nose swc? I've seen that mold in both configurations. Both are just as accurate as the other I just like the sharp edge smacks game a little bit harder. It and the rcbs swc-38-150 (it's close enough that bullets cast from my 358477 will almost fit the cavity s) are my go to molds for my 38s that get shot at game. Both are solid preformers well up into +p area for me. My 358477 is the round edge version and is a shooter in my 38s. Still need to find that mold in a single cavity to hp and scratch an itch I've had to do so.

    I was lucky, Dad had a 358242 in both weights and I really liked the 121 in the 9mm. The little one is great in the 380 auto. I had to get my own so when I moved out I could cast my own.
