Not sure whether this has been asked previously but I have a friend who is now the owner of a Kimber in the above caliber. Need some load info for 150 grain partitions. Scotty, Doc, any thoughts?
7MM WSM

I would start with RL22... It runs really well with 160's, but there are a number of great powders for the 7mm WSM.. Just about the easiest cartridge I have loaded for.
Cartridge : 7 mm WSM
Bullet : .284, 150, Nosler PART SP 16326
Useable Case Capaci: 73.902 grain H2O = 4.798 cm³
Cartridge O.A.L. L6: 2.860 inch = 72.64 mm
Barrel Length : 24.0 inch = 609.6 mm
Predicted Data for Indicated Charges of the Following Powders.
Matching Maximum Pressure: 63000 psi, or 434 MPa
or a maximum loading ratio or filling of 110 %
These calculations refer to your specified settings in QuickLOAD 'Cartridge Dimensions' window.
C A U T I O N : any load listed can result in a powder charge that falls below minimum suggested
loads or exceeds maximum suggested loads as presented in current handloading manuals. Understand
that all of the listed powders can be unsuitable for the given combination of cartridge, bullet
and gun. Actual load order can vary, depending upon lot-to-lot powder and component variations.
USE ONLY FOR COMPARISON !
169 loads produced a Loading Ratio below user-defined minimum of 90%. These powders have been skipped.

RL22 is a good powder for the 7WSM. I use a lot of N560 and N570 with this particular cartridge.
