Snub loads, Buffalo Bore/Speer Gold Dot....
To me, the best carry/protection .38spl snub(J frame) loads are; the Speer Gold Dot 135gr JHP +P, the Corbon DPX, the Ranger T .38spl load, the MagSafe SWAT .38spl, & the proven 158gr lead SWC-HP +P.
The 158gr lead SWC-HP +P is sometimes called the Chicago load or the FBI load because of it's regular use by working cops.
I got a box of 158gr lead SWC-HP +P from Buffalo Bore. The Speer Gold Dot 135gr JHP +P was good also. It was designed for J frame snubs & the sworn LE officers in the NYPD.
