I was given 2 tubs of N320 for free and have ended on a load of 7.5 grains with a 200 Grain cast GM RNFP it’s about 1/3 of the way between a 44 special and a 44 mag load and shoots great indoor at 25 yds out of my marlin 1894 with the standard iron sights.

It's not my faulty, I was just.....
N320 is a lovely clean powder. N310 is similar but the grains are so fine they flow like water- very easy to spill.
I use Trailboss in my 45/70 good load only need 12gr in the case work out lot cheaper
than full load i can tell ya get over 300 loads from bottle
In my 357mag loads using 3gr titegroup with 180gr TC works well
in my Rugger 77/357 very light load work well at 50m
I use 5.5grn Unique under a 240 RNFP good out to 100m
