I have always carried a .38 Spl. as my CCW gun and have made it a point to personally test the bullets I carry in it. I have posted the results here a few times but here is what my actual Chronograph numbers look like out of my 2" S&W M60-7.............
Rem & Win Std. Vel. 158 grain LSWC ------ barely broke 700 fps
Rem, Fed, Win +P 158 grain LSWCHP------ high 700;s - low 800's
Speer Gold Dot 135 grain (short bbl.) +P JHP ------ around 860 fps
Buffalo Bore Std. Vel. 158 grain LSWCHP --------- around 880
Buffalo Bore +P 158 grain LSWCHP-GC ----------- 1025 - 1040 fps.
I have done a lot more than just one testing of these loads and can honestly say that the velocities quoted by Remington, Winchester & Federal on their FBI loads are Hog wash, ESPECIALLY out of a 2" gun! Buffalo Bore's claims are spot on, and Speer's is pretty close too.
Over the last 4 years or so I have been carrying the Buffalo Bore +P 158 grain LSWCHP-GC and yes it is a handful in a 19 ounce 2" revolver with small grips. That said, practice with said loads makes it at least do-able and feasible to be shot effectively. Unless you practice often and shoot this load occasionally to become familiar and sort of comfortable with it, I would say most people are much better off with the Speer Gold Dots. They are still very effective, much easier to shoot accurately, and generate much less felt recoil. That is usually the load I recommend to a Newbie.
I will however say this about the BB +P. It is extremely accurate, the most consistent of all the loads mentioned above, and literally turns your 2" 38 special into a low end .357 Magnum. You just need to be a lot more disciplined when it comes to practicing often with this load.
The thing I dislike about the Speer Gold Dot is that IMHO penetration is marginal at best. The "experts" tout that 11 - 12 inches is the minimum penetration needed, and while the load does consistently do that in pure ballistic gelatin, there are no bones, muscle, tendons, cartilage or clothing in it when tested. The Buffalo Bore +P will penetrate 18+ inches through the same gelatin and so in my own mind that BB is the better load if one can shoot it accurately and rapidly, but if not, the Gold Dot might be the ticket in a 2" snub.
