Winchester Value Pack 230 gr factory loads chronoed an average of 843 fps for five shots fired with a range of 838 to 857 fps. Temp was 58F and the temp of the ammo and weapon were between 69F and 58F.
FWIW, my 625-10 stung my hand so bad with factory 230s that I sold it. I tried it with the Ahrends combats, Pachy Decellerator, and a pair of S&W fingergroove combats. "Ouch" on all accounts, with the Decellerator grip being the most tolerable. I am NOT sensitive to recoil and my favorite handgun is the 1911. However, my Colt Defender and Springfield MicroCompact both have way less of a "sharp" felt recoil than the 625-10. That thing STUNG to shoot.
Further, there have been some 625-10s that cracked the frame at the bottom of the barrel threads above the yoke/crane recess. S&W is NOT replacing the frames; they are offering credit towards some other new S&W firearm.
I am SOOOOO glad I sold mine, although given the very low production and cracked frames taking more off the market, I have no doubt that in future, S&W collectors will bid up the market price of the 625-10 to "Bloodwork" gun price altitudes.
