I've never loaded SWC for a semi-auto, thinking that since it was designed for round nose/ball that there could be feeding issues. I take it that's not the case?
This is why the 185gr Hollow Base RN from Berry Mfg is so popular. You get the ogive shape of the 230gr to insure good feeding, with the lighter weight and cost savings of the 185gr.

The Cartridge. With the stepped SWC ogive shape, it's more important to know where the shoulder is than where the meplat is using the traditional "OAL" measurement method. Luckily the SWC shape/dimensions has become highly standardized over it's 100 year history. Apparently (I say this because this knowledge is the sum of more reading than cartridge construction), you want about 0.030" of bullet shoulder showing out of the case mouth, while the OAL means zilch/ nadda/ nothing.
Therefore, it may help to "optimize" your dies to seat on the shoulder, rather than the meplat. I can do that type work.

The Gun. Also important to note is that there are literally
hundreds of 1911 mag manufacturers out there, while there are very few trusted brands. While feeding the 230gr RN is "easy", the 200gr anything begins to offer complications. And this is especially true of the 200gr SWC. Mags are such an issue in the 1911, that the very first corrective measure is typically to "try another brand of mag". Luckily with the CZ 97, you get a fantastic mag.
So MANY of the issues are related more to the
1911 pistol (especially cheaper import clones) than the
45ACP cartridge. So are we talking 1911 feed issues or best 45ACP ogive profiles for feeding ?? It's important to state up front. On your common "open house" forums the 2 are used interchangeably.
That always leads to confusion and misinformation. Hope this helps.
