    Older Nosler Manuals - .243 105 gr Hot Cor??

    I’m looking for .243 Winchester data for the Speer .243 105 grain hot cor bullet. This is discontinued, and I’m not finding data online. Does anyone know which edition of the Speer manual has this bullet? I have both IMR 3031 and 4064 available I’d like to use.

    Thanks

    I believe that the 105 grain "Hot Cor" was an offering from Speer, and not Nosler. The Speer Number 10 has data for the 105 grain bullet, but not with any of the powders that you listed. Nosler shows some loads with a 100 grain bullet, and IMR 3031 and 4064 but not with a 105 grain bullet.

    Speer #11 is the same way nothing for those powders, but the Lyman#45 has both listed for use with a 100 gr.

    Jim,

    Here is the PDF file for the 105 gr Speer Bullet you ask for. There are 4 pages in this file, Speer #8, Speer #11 and Layman #45 for the 100+ gr Cast bollit & 100 gr Jacketed.

    I can PM you what I have. I should have all the Speer manuals

    I like those two Speer 105 G .243 bullets! I was lucky and able to grab a supply I wont extinguish.

    100 grain data will work just fine, 5 grains in a bullet is not much difference.
