Wow lot of great info here even if it was dug up from the dead.
I bought a cheap savage axis on impulse and trying to work up load using 55vmax (have 500 nbt on the way ) but can’t find a load it likes with cfe 223. It’s what I have along with imr4166 (haven’t opened it yet).
Two powders keep coming up are h380 and h4895. I might have to try and find some.
