i have used 45 ACP MBC 230 gr RN hitek coated softball for several yrs. the loads that work in my 1911 and sig 220 don't feed well in my cz97b so i've learned what COAL works for the CZ. i was still working through the last of my prepandemic 230 gr rn bullets and started on a box from 5/2021. the bullet profile changed. the bullet is "chunkier" and has to be seated much shorter than the previous bullets. old one would plunk in the CZ at 1.25-1.255. the "new" bullet has to be seated at 1.212-1.213 to plunk. will have to see how these shoot before loading more of the same. i hope this doesn't increase the pressure significantly. i would think a chunkier 230 gr RN bullet would have less bullet in the case when loaded to plunk but it looks like the base is deeper instead.
. not too keen on working up the load which is why i stick with the same bullet. if not for the CZ this would be a non issue as the 1911s and the p220 has no problems with longer COALs. anybody else noted the change?
i think i've used 9 mm 147 gr and 45 ACP 200 gr SWC hitek from the same order and didn't notice a chamge in those bullets.
