[QUOTE="RockZ, post: 426215, member: 5750"] I ran some numbers on quickload and it looks like H4831or H4831SC will work better than IMR 4831. You get a 95-100% fill rate and good burn characteristics. H4831SC would be my first choice to try, that way you can stick to the extreme powders. Just work up a load that is in the 2900-3000fps range and work around that. Retumbo and H1000 is a bit slow for the 180gr. VVN560 is also a very good powder for the 180gr. H4350 may also work but you will only get about a 88-90% fill rate. [/QUOTE]
