.32 H&R Rounds vs. Federal .327 Mags: What's the Difference?
I am looking at a Ruger SP101 chambered for .327 Mag & was told that I could shoot the .32 H&R rounds to save money if I wanted to. What's the difference between the two cartridges?

The .327 Federal magnum is essentially a .32 H&R magnum lengthened by 1/8 of an inch.
The .327 Federal magnum has a chamber pressure of around 45,000 psi compared to 20,000 psi for the .32 H&R magnum. You can shoot .32 H&R magnums in a gun chambered for .327 Federal magnums - but not vice versa. Like the difference between the .38 special and the longer .357 magnum, where the much higher pressured round was lengthened by 1/10 of an inch to prevent it from being fired in a .38 special chambered gun and blowing it up.

Will the felt recoil be much different between the four cartridges (Federal .327 Mag, .32 Smith & Wesson, .32 Smith & Wesson Long & .32H&R)?

Yes, as you go from the shorter rounds to the longer ones the recoil will increase accordingly.
Be sure to scrub the chambers good with a bore brush and solvent after you shoot the shorter rounds so that you won't have the carbon ring build up that would cause difficulty in chambering the longer .327 Federal magnum cartridge. Low recoil though is one of the advantages of the .32 H&R and the new .327 Federal magnum cartridge.

So am I correct in concluding that even if this .327 Federal Magnum cartridge "fails" and goes the way of the dinosaur, there are still two other major, relatively inexpensive cartridges available that I could shoot out of a Ruger SP101 (chambered for .327)?
