H322 in a 308 AR?

[dpete]

Does anyone have any experience using H322 in loads for a 308 AR?  More specifically, using it with bullets over 150 grains.  Hodgdon lists a load for 150 and I have found a few references to loads using 168 gr on the web but does anyone have first hand real world experiences with it?  Any info on charge weight, bullet size, primer type, and case would be greatly appreciated.  I've been using CFE223 in my 308 loads and they have been good, but the temperature sensitivity almost got me this past summer (blown primers on a near max load).  H322 is a Hodgdon extreme powder (temp. insensitive) and its micro extrusion size flows just about as well as the ball CFE223 so I'm thinking of making a switch if I can come up with a load that works.

H322 is a fast burning powder. More suited for a 6.8spc round with a light projectile (110gr) or a .223 round.
