Actually, I just checked the Hodgdon website again, and it looks like H4350 is back to being slightly slower than IMR.

H4831 has always been slower than IMR4831, but exactly how much depends on the cartridge and bullet. Luckily, we do have Internet access to lots of up-to-the-minute load data these days.
