I have been out of casting for a number of years and I'm taking a look at the molds I have. I found a Lyman mold (believe I purchased in the early 80s) marked 38 cal RN 121 gr 358242. The mold itself is marked 357. When I look in the Lyman 46th addition of their reloading handbook it shows that mold number as a 92 gr RN. My question is, will this mold work in a 9mm Luger?

Thanks in advance for your help.

Lyman made two version of that mold, one cast a 90 gr. RN the other a 121gr. RN.

From the Lyman #3 cast bullet manual for 9 mm.

Thanks you res45. That is the exact information I have in the older Lyman manual. My question still remaims, will this work in the 9mm?

Being that the data is under the 9 mm section of the manual I would suppose so, you're just going to get higher velocities on the top end loads with the lighter bullet.

If you know what bullet size you need you can change it with the lubrisizer.
I believe most lead 9mm use .356" diameter.

Yes the bullet will work in 9 mm Luger .
Cast and weigh a few to make sure which weight you actually have ,,, the blocks aren't marked . Then use the Lyman Cast Bullet data for the weight you have .
The 90 grain is a little light but useful the 121 more in the middle of the weight and there should be plenty of data for 120 to 124 grain bullets .
It is designed for 9 mm Luger and 380 acp also .
I size all mine .357

The two versions are different in that the 120 grain has two lube grooves where the 90 grain only has one.
