As a note;

I also tried a 125gr Coated RN, .356" dia. bullet from a OAL from 1.06 up to 1.16" with five powders from fast to slow burning.

It was all over the place in my weapon and hit point of aim at 945 and 1046fps with two different powders and two different OAL's, of a total of 30 test loads.

You might be better off with the plated bullets?
