[QUOTE="deerwhacker444, post: 1300863, member: 9117"] Using 48.0 gr. of IMR 4320 gives: [B]AVG: 2729 fps[/B] ES: 61 fps SD: 27.06 fps I have slugged the bore and it runs from .311 to .312, that's why I'm using the .311 bullets. It shoots great with 48 gr. but I was trying to pump the velocity up a bit but I didn't know where the max was. [URL="http://stevespages.com/page8a.htm"][B]Steve's Pages[/B][/URL] lists the top end for 4320 at 51.0 gr. but that's with a .310 bullet. I'm using .311. IMR's website doesn't list and IMR powder for 150 grainers,..I checked that initially. Thanks for the replies.... [/QUOTE]
