From a burn rate perspective, in your experience, where would you say this powder stands in comparison to Win 760.

 

[Ironworker]

Slower . Its in the area of H4350 .

Any primer preferences? or does Hodgdon recommend a magnum primer? I could see how Staball would be a real good powder for .22-.250 with 68" & 75's. Did the 42.5g make for a compressed load with the 55 Si GK in the .22-250? I appreciate this post.

As soon as I can get some 6.5 StaBall I will try it out in my .22-.250 with 75 ELDM's & CCI 200's & CCI 250's. I will compare powder densities by setting my measure at some big amount of probably 100 grains of H414 and weigh the same volume of StaBall, H4350, & Re16.

It should be a great powder but superformance is super. My 22-250 with 69tmk at 3550 fps = low 1's-low 2's. I will be trying staball soon.

Am anxious to get some of it and give it a try in my 220 Swift and 17 Remington. WD
