I worked up a load for the 325 wsm, 180gr TSX using IMR 4007 SSC powder. I could not find any load data for this combo so I looked at published load data for other 180gr bullets and went from there. I loaded and shot the following set of 3:
Winchester brass trimmed to 2.090, WLRM primer, .035 off the lands, IMR 4007 SSC
about 3 inch group
about 1.25 inch group- see pic
about a 3 inch group... huh ??
Published load data for the 180 TSX with other powders comes in at about 3070 or 3080fps. It looks like I'm there with 65gr IMR 4007 SSC. Barnes recommends .050 off the lands. I'm going to mess around a little more just for the fun of it to see if I can tighten up the group a little more. I'm not sure what;s up with the 66gr load. I may have to try those again incase a I messed something up. The Kimber shoots accubond factory loads sub moa. I'll see if I can get the TSX's there. If not, no biggie, the 65gr load the way it is will be headed to the Brooks for sheep in about 5 weeks
