rw,
just fyi, the rest of the data from the speer #11 manual: test weapon is a ruger security six w/ 6" barrel, bullet is a 125 grain soft point, primer is a cci550 (magnum primer), max powder load is 19.5 grains of 2400, muzzle velocity is 1555 fps.
caution: this data was published before saami revised their pressure data in 1992. the above load is probably above current safe pressure levels.
