The .300 WSM pet load thread won't open. I need recipes for 180 grain Accubonds and Partitions for a new rifle. I seem to recall quite a few people using H4350 but Nosler provides no data on its website for either of the 4350s and 180s. Obviously any other combinations are welcome. Thanks in advance.

Check alliant and Hodgdon sites?

Worst case Under " Good .300WM loads" I posted a plot of quickload data barrel times.
It shows how sawtoothed adjacent "burn rate" powders might (depending on quicksand algorithm) be.

There is a hole inn the data for Imr-4350-H-4350 but A4350 is there. It might give you a feel for what powders may be similar to what you are looking for.

JMH,

You have a lot of good options. This will get you in the ball park.

Code
Cartridge          : .300 WSM (CIP)
Bullet             : .308, 180, Nosler AccuBond 54825
Useable Case Capaci: 70.084 grain H2O = 4.550 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 105 %
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 !

67 loads produced a Loading Ratio below user-defined minimum of 75%. These powders have been skipped.
Powder type          Filling/Loading Ratio  Charge    Charge   Vel. Prop.Burnt P max  P muzz  B_Time

You didn't use logic or reason to get into this opinion, I cannot use logic or reason to get you out of it.

You cannot over estimate the unimportance of nearly everything. John Maxwell

My go-to load with the Partition/Accubond in a variety of 300 WSM's was 64.0 H4350 for around 2,980, or 64.5 RL17 for 3,030.
