If your google fu is strong you can find a couple on the web comparing the two. Those I have read indicate that 4451 is not as insensitive as H4350, but not too far off and certainly better than, say, IMR4350. BUT those I have read are flawed in that they only chill the ammunition, not the rifle.
Tzone, as I mentioned in the other thread, try H4831 with heavy bullets.
