Mouse fart loads , any tried and true suggestions?
Now that my gas checked reduced power econo load works well enough I want to work on a 1,000 to 1,100 load. I have seen Unique oads listed but no FPS on really light ones.
Found a very old post where 4gr. of Blue Dot was giving 1,150 in a 24" bolt action and was extremly accurate with MJ HP at 200 yards plus.
Hogdon list Trail Boss , Titegroup and Clays reduced loads in thier on-line data base. Guess I need to go powder shopping. I have about 1/2 pounds of Unique which is between 30 and 40 years old and it still looks and smells fine but not sure it is the base to use for load development. One nice thing is that these loads should not need gas checks so amount of time required goes way down along with powder cost and cases should last forever.
