I had real good luck with a 155 grain lead RN using HP-38 or Unique. Both mid-range loads according to data. Good function and fairly accurate. I had no chrony then so I can't tell you what they were traveling at.
Don't have the caliber anymore but still have around 600 rounds of ammo for it.
I also had good results with Hornady XTP 180's and HP-38. Very accurate.
Edited: It just occurred to me that I am not in the reloading section anymore.
As far as factory goes, I only bought a bit of that. Gold Dots functioned well and showed good accuracy from my Sigma. Blazer Brass is what I bought for cheap rounds. Functioned fine for shoot em up type ammo and the brass was reloaded for the above rounds.
