Look for Seafire Blue Dot data on the web.
Accurate Reloading Forums had listings of several different calibers he worked up with Blue Dot.
I made a loading to match Remington's "Reduced Recoil" using Hornady 130 bullet and 2?.? of Blue Dot. Quick load says I should be getting about 2400 fps and there is little recoil.
13.5 grains of 2400 and a 115 cast boolit will give one about
1550 fps (chronographed data) and one hole at 50 yards for 5 shots.
I would suggest a few hundred rounds of unique or 2400 or similar powder under a light cast boolit sized about 0.309- 0.310" with good ear protection.
As some one said above be EXTRA careful with the highly reduced loads as some could be a TRIPLE charge and easily fit in a case. That is the beauty of Sefire's loads with Blue Dot, a double charge will be easily detected.
Good luck and if you get to shooting an accurate cast boolit load with reduced charges you may find "plinking " with the aught six to actually be fun
