kjkisd, As noted above, loading for 32 H&R performance in a 327 Fed Mag case is comparable to loading 38 +P ammo in a 357 Mag case. The velocity range for 32 H&R is from 900 to 1100 fps. This can easily be achieved with any mid-burn rate powder, such as Unique, Universal, AA#5, or Power Pistol. Use the reloading manual's data for 32 H&R and you can't go wrong. A 32 H&R Mag develops a max pressure of 23.5k psi, whereas a 327 Fed Mag develops 45k psi. As you can see, even the hottest 32 H&R mag load will be well under the pressure rating for the gun, so you won't hurt anything.
Primers are a different story. If they were universally interchangeable, there would only be one type for small and one type for large, however manufacturers make Standard and Magnum in both large and small pistol, plus rifle primers in the same configurations. Each type of primer has both a flash temperature and a flash duration that best matches the intended powder. To keep with "best practices" as it pertains to reloading, I never use rifle primers in handgun cartridges nor handgun primers in rifle cartridges. I always use Standard Pistol primers for fast or medium burn rate powders and Magnum Pistol primers for slow burning powders such as W-296, H-110. Lil'Gun, or 4227. If you violate this basic concept, you could end up with something you didn't expect.
