Yes, it was .204 brass that I was referring to. I just picked up a nice Remmy in .204 & I think I will try the A2460 in it as the 1st load I work up for it. Been wanting to try this particular powder in a .204 for quite some time now. They put this powder right along side the 8208 in the burn rate charts and I know that lots of fellas are claiming their .204's love eating the 8208. Regardless, I'm soon to find out!
