Load help please: RD 432-265 in Dan Wesson 44 mag

[Jeffrey]

Good day,
Some time ago I bought a Ranch Dog 432-265 (GC) mould for my 444 Marlin. When I did I saved Ranch Dog's data for the 444. Now I am wanting to load this boolit for a Dan Wesson 44 magnum revolver. At the time of mould purchase I did not record the 44 magnum data. These revolvers have a longer than usual cylinder, so typical COALs and case volumes do not necessarily apply. I am wanting these to be full power (North American) hunting loads. My Speer #14 has 250gr (non-GC) data, Lyman Cast #4 has data for a 255gr (GC) boolit and a 265gr (non-GC) boolit, so that is getting me started. I am hoping someone has data for this boolit in this cartridge, dare I hope, in this revolver. Suitable powders on hand are Acc #9 and 2400. I would prefer to use the #9 for this application as the 2400 has been hard to find and is reserved for my 357 magnum.
Thanks in advance. Jeffrey

As per Ranch Dog's Load notes, Accurate No. 9 max is 17.8 gr. Alliant 2400 max is 18.0. These were tested out of a Marlin 336-44, COL is 1.56.
I use this bullet and a plain based version out of my Marlin 1894 and Ruger Super Blackhawk but I only use H110 and Unique in them.
