I am about to load about 500 MBC 9mm LCNs for my XD. In my trial loads last year, I found (according to my notes) that an OAL of 1.11 was max. I just did a box of 50 as a sort of "warm up" run with the intent of shooting some of them first to confirm my data before the larger run. I loaded those to 1.080.
As for accuracy, the error factor represented by the shooter (me) sort of makes estimating that value a very approximate exercise in all my handgun reloading. But my notes show the cone bullets shooting just fine.
Your CZ may require a shorter OAL than my XD, from what I've read around here. But I see no reason the LCNs wouldn't work. Like you, I switched from Small Ball to LCN because I didn't like the very deep seating required to use the RN bullet shape, even in my XD (can't recall the OAL right now).
bds, the stalwart of this forum, provided me the samples of the MBC types with which I did my first test loads, as he is offering to you. That nice gift included some SWC 9mm, which I was partial to, until I seemed to get keyholing with them. Instead of solving that problem I just used the Small Ball, and now the LCN.
I was thinking that, after the storm has passed, Missouri Bullet might want to offer sample packs of their different bullet types, as Precision Delta does, just so folks can try everything without buying 500. bds is a fine ambassador for MBC, but we have to leave him time for his yeoman work on tracking component availability in every nook and cranny of these United States .....
