34 to 35gr of 5744 gives me ~1600fps out of a Cowboy (26").
So will 49-50gr of Varget. 37-38gr of RL-7 gives me ~1600.
40gr of H4198 (apparent recoil feels higher) about same.
These are loads I found in my "Bear Defense" cartridge box. Your results (and loading procedures) may vary. These are some of my loads and I do not recommend them to anyone other than myself.
Would recommend work ups for each powder.
These days only shoot cast WFNGC or solids for 1600fps +. Plain cast HSMs for under 1500fps loads.
