Recoil is largely subjective. Fast burning powders generally have a snappier recoil than do slower powders. Short-barreled weapons require faster powders to maximize the amount of powder burned while the bullet is in the barrel.
Slower burning powders give more velocity in longer barrels at lower pressures than faster burning powders.

All wrong
I'll ask this. Given that a whole lot of people are saying that the .327 is almost as hard hitting as a .357, is much lighter, has much lower recoil, and does use fast powder, how do you explain it? All these people can't _all_ have thick palms and beefy wrists.
By the way, I have no interest in buying a .327, so you don't need to assume anything in that direction.
I'm not sure who you're addressing your remarks to. I hope everyone here already knows recoil is made up of many factors. But please note that in my OP I didn't say powder burn rate was the only factor involved in perceived recoil, and I have no idea why anyone might assume otherwise. I only asked about the apparent claims that (assuming it was one of many factors such as gun weight, etc., etc., etc., etc.) that factor contributed to lighter recoil as many have said. (Even those who say so never say it is the only recoil factor on earth.)

Explain what, specifically?
Perhaps the lighter bullet? Gun-to-bullet weight ratio? Slower burning powder with a longer gentler pressure rise curve? Less powder ejecta?
I'm not certain what the question is; this? "Do fast burning powders always cause less recoil than slow powders? If so, why don't all cartridges use them?"
No. Not always.
Fast burning powders have less ejecta (exception: Titegroup, lowest ejecta of all) which is a component of recoil, which means THAT part of the recoil equation is always true. Lighter charge weights have less recoil than greater charge weights.
But the other factors often erase any benefit of the lesser charge weights, like the time the pressure takes to build, or the shape of that curve.
So many factors......

Have two 2" J-frames...
one's SS frame the other is a Aluminum frame.
Using 125gr commercial ammo, Std. Pressure, the Al frame has more pronounce recoil.
With short barrels, compromises with powder is used to insure that combustion is complete as possible in the shorter barrel with minimum flash.
review the reloading manuals, most barrel lengths are 4" or better.
Would be nice if an ammo company would make a 140 gr lead HP capped with a gas check, using std. pressures.
