I’ve seen the .45 Colt dismissed as weak as well, including the percussion handguns that are fairly similar (my Pietta Remington NMA holds 33 grns weight of 3F Olde Eynsford, which is quite similar to Swiss, and my 195 grn WFN bullet with a bit of additional space). This should outpace the .45 Schofield and late .45 Colt loads that used 28-30 grns of powder and the 230 grn bullet, which was still fairly potent.
