[QUOTE="dwm, post: 32807, member: 1136"] FYI, Hodgdon publishes an annual reloading manual for about $12. The 2004 version has loads for almost all of the new Ultra/WSM versions. For a 7MM RUM with a 24 inch barrel and 162 AMAX using Retumbo as a powder it shows: Start: 89 GR - 3009 fps (162 Hornady Spire Point) Max: 95 GR - 3223 fps The AMAX likes to be seated into the lands. I would use a Stoney Point seating depth gauge, a magic marker, smoke from a candle or whatever works for you and find a seating depth of ~0.005 into the lands for your chamber. Then I would start with loads using 89 grains of Retumbo and work up using the ladder method. (You can find the ladder method on this web site by doing a search.) My 7MM RUM is doing quite well with 92.5 grains Retumbo and Federal Gold Match 215 Magnum primers. [B]Yours may be different so start low and work up, especially if you seat them into the lands.[/B] Doug [ 03-29-2004: Message edited by: dwm ] [/QUOTE]
