Looking for load data for my model 70 26" 7mm Rem Mag and the 168 ablr. I have rl22, 7828, and hunter on hand. How far off the lands are you guys finding accuracy?
Cartridge : 7 mm Rem. Mag.(SAAMI)
Bullet : .284, 168, Nosler AccuBond LR 58623 G7
Useable Case Capaci: 71.513 grain H2O = 4.643 cm³
Cartridge O.A.L. L6: 3.290 inch = 83.57 mm
Barrel Length : 26.0 inch = 660.4 mm
Powder : Alliant Reloder-22
Predicted data by increasing and decreasing the given charge,
incremented in steps of 2.0% of nominal charge.
CAUTION: Figures exceed maximum and minimum recommended loads !

The 7 RM should be fairly easy to load with this particular bullet. It may not be fussy at all. I may need to take a good look at this bullet in my old 7 RM.
Cartridge : 7 mm Rem. Mag.(SAAMI)
Bullet : .284, 168, Nosler AccuBond LR 58623 G7
Useable Case Capaci: 71.513 grain H2O = 4.643 cm³
Cartridge O.A.L. L6: 3.290 inch = 83.57 mm
Barrel Length : 26.0 inch = 660.4 mm
Predicted Data for Indicated Charges of the Following Powders.
Matching Maximum Pressure: 64000 psi, or 441 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 !
34 loads produced a Loading Ratio below user-defined minimum of 90%. These powders have been skipped.
