I’ve got test loads of N555 with Sierra 142 Match Kings - I just got to get to the range again .it is 100 % Temp Stable and has Copper eraser in it according to its maker and also claims it is the BEST 6.5 CM powderUnderstood. Curious to try it, just not sure it's worth it. Is it more of a consistent burn over the Hogdson or IMR? Or more temp stable.
