I just took a close look at the Buffalo Bore standard pressure 38 special 125 gr load -- 20E-20
The bullet looks identical in a side-by-side comparison with 125 gr 38 special +P Speer Gold Dot ammo.
I believe BB is sourcing the bullet from Speer. I've heard that said before, and now I believe it.
In looking at BB ballistics number they showed this standard pressure load making 921 ft/sec from a 2" snub .
Pocket guns and gear has a test of the Speer 38 special+p 125 gr load clocked at 900 ft/sec -- and it shows good expansion in gelatin.
That leads me to believe that the BB 125 standard pressure load is a good choice for 38 snub nose revolvers -- particularly those not designed for +P.
