for .223 bullets in 36 & 40 gr, I like H110
for .224 bullets in 50, 53, & 55gr, I like 2400
I use mostly Nosler and Sierra, but probably should work up something for the 50gr zombies I have.... or buy the 40gr zombies before wes gets rid of all of them again
I tried 50gr vmaxes out of my hornet, they shot well enough, but had much better performance out of the 40gr.
