My grandpa has made a "suggestion" for me to load him up some .44 mag ammo as a Christmas gift for him to use out of his old model vaquero. It was one of his favorite handguns to shoot years ago but his failing health has left him unable to enjoy this firearm for the past few years.
Earlier this year I made him some rounds loaded with 7.3 gr of unique and a 248 gr boolit (the lightest boolit I can cast) and he said those rounds were a bit to much for him. This is the lightest load that I have found data for out of a magnum case. I will reset my dies for .44 special if need be but would rather not if it can be avoided.
The powders I currently have that I feel could work are win. 231, HP-38, HS-6 and unique. Again the lightest boolit I can cast comes out PCed at 248 gr and I'm looking for a target velocity around 750 fps. The 7.3 gr unique load chronoed at 825 out of his firearm.
I'm not looking for specific loads but a source of load data that I don't have. None of my books offer any data on 231or HP-38 in that weight boolit in the mag case but I can find it in the special case.
Thanks in advance for any advice or source of data provided
