I think it's too heavy but some guys will run them, depends on the gun. I would look to a 90-105gr for 380 use. The RCBS 2cav 95gr is an exc mold.
Lyman has 124 grain cast data in the latest Cast Bullet Handbook. I loaded a handfull on my 9mm dies just for ****s and giggles to plink out of my buddy's 380 and they worked fine other than issues related to using the wrong dies (neck tension).
I use a Lee 2 Cavity 105gr (or whatever it is) for .380. It's perfect.
Lee has a 102gr RN mold for .380 that will work but its only a 2 cavity.
I want to experiment with some heavier weight bullets in .380, like the 115gr XTP bullet. I'm sitting here with a 90gr XTP, a 124gr XTP and a .380 case. The 124gr is a lot longer than the 90gr which will take up a lot of case space which the .380 don't have a lot of to begin with.
I was in your position a few months ago. I was going to start casting for the .380 and started to think about how many rounds I would actually shoot. When I weighed what it cost to buy the mold, sizer and thought about my time I decided to order 1,000 bullets from Missouri Bullet. It's amazing how long that many bullets last when shooting through a pocket pistol.
That is why I got the Lee 2cav for my .380. It's just not worth the expense. But I already cast for 9mm so the sizer is the same. One $20 lee mold and I am making my own for .380 as well.
Wait wait wait! Doesn't the CZ have polygonal rifling?
Yes, and therefore will be an excellent choice to shoot cast bullets in.
I don't have experience myself shooting cast bullets (always used jacketed) through polygonal barrels however I will in the future. It appears to me like the very experienced reloaders put a lot of cast lead through poly barrels with zero issues and the inexperienced say you can't shoot cast bullets through poly barrels. If you do get leading with the polygonal barrels it looks like it would be easier to remove the lead vs a traditional rifled barrel.
