Following is with 240g SWC and CCI-300 out of 6.5" barrel
7.5g of Titegroup ... 1040fps.
8.0g of Titegroup ... 1080fps. I had this load marked as accurate. Load I use if Titegroup.
8.5g of Titegroup ... 1135fps
9.0g of Titegroup ... 1182fps
Single digit SDs with above loads.
You did good. No need to 'magnumize' if the 8.1g load is 'accurate' for you.... If is stiffer than a factory .44 Special, but not quite a magnum load. No need to 'hard crimp' this load either.
10g of Unique ... 1136fps (my current go to load for .44Mag) . Just enough to know you have a stiff load yet can shoot all day.
19g of 2400 ... 1265fps (low end magnum range of .44Mag)
Never have used H110 or 296. I am way past having to shoot hand stinging loads for enjoyment
