Thread: Seating Stem numbers

  1. #1

    Seating Stem numbers

    I have started to pick up 310 hand tool dies for 300 Savage, 303 Savage, 30-30, and 30-06.

    The seating die for the 300 Savage and 30-06 both came with a #366 stem in them. The old Ideal quickref only lists the #366 stem for a 8mm.

    I'm hoping that I really only need 3 seating stems, one for spire point, one for round nose, and one for flat tip .... what number stems should I look for:
    1) Spire Point
    2) Round nose
    3) Flat tip

    Thanks, Keith

    You can easily judge the character of others by how they treat those who they think can do nothing for them.

    It's not hard to adapt seating stems. A bit of hot glue or epoxy applied to seating stem. Press in the bullet. Let set. Remove bullet.

    if you look in older ideal manuals at the 310 ref chart the mold has a seating stem that works with it. such as the 450 seating stem is used with the 225450 mold that is used in calibers from the 22hornet and 218bee through 220swift or the 414 stem is used with the 311329 and 311414 molds in calibers like 308 and 30-06. these are examples.

    Thank you; now the numbers on the quick ref make more sense to me. I located a pdf showing all the old Ideal mold numbers, grain and a picture of the bullet profile. It appear the 310 seating stems were numbered with the last 3 digits of the mold number of the bullet they are associated with. The 414 stem aligns with Ideal 311414, a 150gr spire point gas-checked bullet mold. The 329 stem aligns with Ideal 311329, a 185gr Spire point,gas-checked bullet mold. The 366 stem aligns with Ideal 320366, a 176 spire point gas-checked bullet mold for the 8mm.

    The 466 stem aligns with Ideal 311466,a 153gr gas-checked round nose.

  7. #7
    The 241 stem aligns with the Ideal 308241, appears to a 30-30 158gr plain bass RN cast bullet/

  8. #8
    the 413 aligns with the Ideal 311413, a 169gr Spire point gas checked bullet mold

  9. #9
    The 418 stem aligns with the Ideal 257418, a 100gr gas-checked spire point bullet mold

  10. #10
    The 388 stem aligns, with the Ideal 257388, a 80gr gas-checked spire point bullet mold

  11. #11
    The 450 stem aligns with the Ideal 224450, a 47.5gr Spire point gas-checked bullet mold.

  12. #12
    The 367 stem, aligns with the Ideal 228367, a 60gr gas-checked spire point bullet mold

  13. #13
    The 414 stem aligns with Ideal 311414, a 150gr spire point gas-checked bullet mold.

  14. #14
    The 329 stem aligns with Ideal 311329, a 185gr Spire point,gas-checked bullet mold that I believe was made for the 30-06.

    Lyman Third Edition Cast Bullet manual has a chart listing the top punch for most of the moulds.
    Lyman Fourth Edition Cast Bullet manual has a chart listing the top punches for moulds still in production (not many!) and also top punches for moulds made by other mould makers. Seating stem numbers are the same as top punch numbers.
