I am wanting to know what are the best powders to use with 140 grn and 160 grn AccuBond when loading for a 7mm WSM, as in does anyone have a favorite powder that usually works for them.
I am running RL22 in my 7WSM. Getting about 3100 out of the 160 AB pretty easily and accuracy is excellent. DF has a good point of trying RL25 though, his targets speak for themselves. Another good one to try would be Magpro. I am thinking it would excel with the 160's.
I don't load for the 7WSM (though it's on my "must have" list) but I'd think you could make very good loads with the powders already mentioned, or also with IMR7828, or H1000, or perhaps Retumbo or even US869. I am pretty sure when I get a 7WSM I'll be buying Quickload to go with it, too.
Cartridge : 7 mm WSM
Bullet : .284, 140, Nosler AccuBond 59992
Useable Case Capaci: 72.982 grain H2O = 4.739 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 107 %
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.

i use imr7828.
67 gr behind the 150 scirocco gives me 3100 fps
68.5 gr behind 140 gameking gives me 3200 fps
these are most accurate loads, i can add 75 fps to both loads
without pressure signs, but i get a bit less accuracy.
