Do you still want to shoot center fire rifles? I make 'gallery loads' with light bullets (100-110 gr) and reduced charges of power. Makes my 30-06 feel like a .22.
IMR 4895 can be reduced by fully 30% for velocities down to 2200 fps....
SR 4859 can be loaded in the 1500 to 1700 fps range.
Unique can go even lower but I haven't tried it.
I have a light rifle (Savage), therefore it kicks with full loads and my wife is sensitive to recoil and blast.
I just like to shoot them because they are really fun. So you might want to save out some cases if you think you'll try this.
