I know that the 135gr +p SBGD is the prefered round for use in snubnose revovlers, but I was wondering how extensively it has been tested? Brass fetcher puts it penetrating right around 10" in BG, the Speer catalog puts it around 11" IIRC, DocGKR puts it around 13". That seems to be fairly inconsistent, or is that the norm for this type of testing? Is it recommended not because of the penetration but because it is one of the few that performs well in denim test as well as in BG? Thanks, I was just curious.
