I have a Hornady book that lists 16.5gr H 110 as the max load with their 158grm JHP. Velocity from an 8 3/8" S&W Model 27 is 1250fps.
Primers are Fed 200

Same gun with their 160gr FMJ shows a max load of H110 as 15.9gr for 1250fps.

Another edition shows 15.6gr HG110 as max with the 158gr XTP from an 8" Colt Python. Velocity 1250fps. Primers are Win.

I have a Speer book showing 17.5gr H110 giving 1272fps with their 158gr fired from a 6" barrel Ruger Security Six. Primer is CCI 550.

Point here is different tests, different guns, different times, show different results and what is in the loading manuals is what they did, but its not holy writ and may or may not be what your gun does.
