Blue Dot in Reduced Loads

Here is a formula for rifle cases that holds true for blue dot..

Fill the case with Blue Dot until it overflows then level it off until it is just filling the case mouth and weigh the powder on your scale. That is 100%. Blue Dot can safely be loaded anywhere between 10% to 50% of that amount with safe pressures. Of course it is important to have a bullet appropriate to those velocities.

This is a convenient way to make .22 WRFM loads in your .223 Rem. However, It is easy to double charge a case and that can be BAD. One should work up, be careful and verify this info elsewhere. If something goes wrong with ammo you loaded you can presume that you did something wrong.
