140gr Underwood Xtreme Penetrator (Philips head mono metal).. 1,422 fps avg ( 5 fps ES) -- two rounds
158gr Horn Xtp - 15.0gr A2400 Std small pistol, new Starline...
1,316 fps avg (49 fps ES) -- six rounds
165gr CSWCGC (358156) - 13.0gr A2400 New Starline ...

185gr LFNGC (Beartooth), 15.0gr Lil'Gun, CCI 400 New Starline.. 1,228 fps avg (14 fps ES) two rounds
200gr WLNGC (leadheads), 13.4gr H110, Fed 205, New Starline.. 1,102 fps avg ( 4 fps ES) two rounds
200gr WLNGC (leadheads), 14.4gr H110, Fed 205, New Starline.. 1,155 fps avg ( 5 fps ES) two rounds
(purported to be the Doubletap load info)
200gr WLNGC (leadheads) handload with Lil Gun
. 1,266 fps avg ( 2 fps ES) -- two rounds
Load data not given -- maybe too much of a good thing. Spent cases fell from chambers, and no obvious signs of over pressure. Recoil was heavy. Don't even know if this stabilizes.
If even needed, I would vet for crimp jump, and limit useage of the 180, 185, and 200gr loads in J,K, & L Frame guns.
Also ran two Buff Bore 180s thru 16" Rossi M92 carbine
. 1,894 fps avg ( 6 fps ES) -- two rounds
Larger sample would change results but probably not a great deal.
Note: reran 165gr/13.0gr A2400 with new components with the above results.
Originally bought the 200gr LFNGC Leadheads to load in my Ruger Maximum. Got curious, so loaded some in the .357 mag. Havent put any on paper, but no problem hitting various shaped steel plates at 28 yds offhand with the 2 Ύ.
Was surprised at velocities from the 2 Ύ bbl.
Looking forward to 03RN's impressions.
