Thread: useing powder equvelent charts

so I picked up a 44 magnum a few months ago with a pack of factory ammo for brass and have shot them all so ready to load some up
I have some 240gn bullets and some adi ap100 powder I use in my 357 and 38 spl loads id rather not buy more powder for 44 as its just another expense and I don't give a crap about speeds etc for just a plinking gun adi dose not list ap100 as a powder for 44 however adi lists IMR SR 4756 as an equivalent and there is plenty of data for SR 4756 in 44 mag

so how do I go about using that info to make a safe plinking load?
