Has anyone tested these two powders for velocity?
H4350 shows higher velocity in the '06 than IMR4350 at lest in my books.

I have done a little testing with the two 4350 Powders in a couple different 22" Barreled .30-06 Rifles. I obtained more velocity with H-4350 than I did with IMR-4350. 150gr. Nosler Ballistic Tips were used , and I believe the charge weight was 59.0grs. (but I'd have to look to be certain). The difference in velocity was slightly more than 100 FPS if I remember correctly (again I'd have to look it up to be certain).

I've switched over to Accurate's XMR4350, it's more reasonably priced than the other brands.

How does the AA 4350 compare as to acuracy with IMR 4350. I have been considering the change as well.

I have used IMR4350 & AA4350 in my 309JDJ and they both produced great results. Hornady's 5'th edition reloading manual lists the following as MAX. loads.

AA4350 51.9 grs
IMR4350 53.0grs
