[QUOTE="DaveB, post: 3895404, member: 5958"] Yep I keep forgetting. IMR7828 has a problem in that it bridges a bit worse than other powders-I think it is the worst at bridging of any powder. Hodgdon decided to fix this by cutting the extrusions into smaller pieces (SC short cut and SSC which is super short cut). Now all the data sheets and so on make no distinction between the powder types but caution is recommended. If you have been loading IMR7828 and are going to try IMR7828 SSC, you should do what you always do when you change a component in your loading process. Start at the lowest recommended level and move up, watching for over-pressure signs such as cratered primers and sticky extractions. [/QUOTE]
