Some should reread this section of the article by Brian pierce that was quoted by the op before posting” use 327 brass in a 327 revolver!” There are methods to the madness
“Some readers may be wondering: Why bother developing “+P style” handloads in the .32 Magnum when we have the .327 Federal Magnum? There are several reasons. First, the .327 can be very accurate; however, many loads – including some factory loads – have very high extreme velocity spreads and only offer mediocre accuracy. A savvy handloader can certainly develop loads that address that problem, but the .32 Magnum does not suffer from this malady. Rather, with any respectable load it usually exhibits extremely low velocity spreads and impressive, ragged-hole 25-yard groups. Second, Starline cases are readily available and cost less. Third, the cartridge uses lighter powder charges and produces notably less muzzle report. Fourth, the shorter powder column of the .32 H&R is less sensitive to powder positioning with all loads, including full-house, midrange and light target loads, resulting in outstanding overall accuracy. Fifth, cases extract and clear the chamber easily. Call me old fashioned, but for several experienced-based reasons I prefer traditional six-shot revolvers, including the Ruger Single-Six, USFA Pre-War SAA, Smith & Wesson Model 16-4, etc.”
