Large numbers of .45 auto shooters use WST powder for target loads (which is essentially what we fire in WB). With a 200 grain bullet, you can go well above the necessary velocity for WB. (A 230 grain, you have very limited range of data for getting a safe pressure load that also is safely above the Power Factor). WST burns clean and cool, compared to TG.
The Semiwadcutter bullet will not be as versatile as a Truncated Cone or Round Nose Flat Point. Using the H&G 68 design 200 grain SWC, load that so the top edge of shoulder comes just barely above the mouth of case and taper crimp down to about 0.471" OD right at the mouth. At least, that was my recipe for 30 years of shooting the SWC, before switching to TC design that is a little more forgiving on having an exact seating depth. The sharp shoulder on a SWC seated slightly long will jam on the rifling that starts very close to the chamber on a standard throated 1911 barrel. Leading to failure to chamber during the last 1/8" of slide travel.
And, WST will work fine for a light loading in the .44 Mag, too.
Good luck, GJ
