This is where I get them. From Midway.

They shoot well out of my A&H. I did kill a deer this year with
this bullet. It was a neck shot though. I did not recover the
bullet. I don't know how they perform with a perfect behind
the shoulder shot. They are kind of high dollar if you ask me.
I used the MMP HPH 12. If I am still in Iowa next year, I will
probably try them out of the HPH 24.
