IMR-4320 has become my go-to powder after I was given an 8-lb keg of it. So far it's doing a great job of keeping two 308 win rifles fed, and recently in the 35 rem with a good dose to shove 250gr cast gas checked slugs down range. All in all I'm very pleased with it. It now holds the title as my most accurate powder for a load in a heavy barreled Schultz and Larson target rifle in 308. I'd post a picture of the group if this forum site wasn't so cumbersome on uploading photos. 5 shot group at 100yds was 0.3" on sandbags. This powder is capable of stacking shots in the right setup.
