The 340 Wby is one heck of a cartridge for elk.
With the 225 gr AB-
RL 22 Start at 82.0 grs and work up to a MAX of 86.0 grs.
With the 250 gr PT-
RL 22 Start at 79.0 grs and work up to a MAX 83.0 grs.
You might also look at IMR 7828, which Nosler list with both bullets as the most accurate powder.
Have you considered the 250 gr AB? The BC is .575 and it shoots like a dream in my 338 RUM. I just checked my 200 yd zero at 100 yards this afternoon and put 2 of these bullets in the same hole.
Cartridge : .340 Weath. Mag.
Bullet : .338, 225, Nosler AccuBond 54357
Cartridge O.A.L. L6: 3.675 inch or 93.35 mm
Barrel Length : 26.0 inch or 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.

I settled on 86.5 grains of IMR7828 with the 225 AB.Went out Sat. morning and dropped a nice 3x5 in his tracks at just under 500 Yds. I have to say the Leupold B&C retictle played a big role too. :lol: :lol: :lol:
