From Handloader issue 274 (October 2011), "Magnum Revolver Loads with Alliant Power Pro 300-MP", pages 20-23, we have a little bit of data.

.327 Federal loads were tested in a 7.5" Sparrowhawk.
No OAL is stated.

Code:

Bullet                   Charge (grains) - Velocity (fps) - Primer   -    Case      -   Velocity Spread (fps)

At first glance that data is a bit disappointing (to me - compared to my 5.5" Blackhawk). But, a statement within the article shows that this particular Sparrowhawk is producing slow velocities with factory ammo, anyway: "Incidentally, PP 300-MP is the only powder I have tried that made it possible to duplicate and exceed .327 Federal Magnum factory loads..."

I take that to mean that the 115 gr Gold Dot load is exceeding factory velocities in this Sparrowhawk (though still short of my Blackhawk's 1,480 fps - oddly).

So... if one of us has a wild hair looking for an anal orifice to enter... PP 300-MP may be worth a shot.
