In the next-to-most recent Lyman manual, under .44mag, it lists a max of 24.5 gr. of H110 under a 240gr. JHP and 23.5 gr. minimum.

I loaded a batch of an even 24 gr. and got flattened primers and sticky cases in my 629 Classic DX. I looked up the parameters for W296 and it listed a min. of 23 gr. I went with that for my next batch since both powders are the same. The primer and case issues went away.


Oddly enough, that load was the favorite of both my 629 Classic DX and my Marlin 1894. Go figga!

I have stepped back one grain on my W296 loads as of recent.
The accuracy is the same or better and the pressure is "normal".
These are .44 loads. 23 instead of 24 under a 240. 26 instead
of 27 under a 200.
Why tickle the dragon?
