My .32 shot very similar to that with 20gr. 3F GOEX, but that single hole (5shot, maybe 1/4" CtC) group opened up to 2" at 50 yards.
I had to increase the load to 35gr. to get it to like shooting at 50yards. The 25 yard groups remained the same with the heavier load,
thus I used 35gr. 3F GOEX for all ranges.
