quick load - 257 Weatherby

[SenderoAg]

First time on the board. I’m sure not what a “Quick Load Data” report is.
Looks like it will give me the load data and the muzzle velocity of that load.
If so, can someone run one for a 257 Weatherby – 24” barrel
110 Grain AccuBond
H1000 powder – My current load is 71.7 grains. Not sure what the muzzle velocity is, but getting 5/8” groups.
I would appreciate it very much.

Welcome aboard.

QuickLoad is a program that calculates velocities and chamber pressures (among other parameters) with the data you input. It does provide an approximation of what to expect. There are a number of refinements that can be made to produce very accurate results.

With your current load, the projection would yield these numbers:

Cartridge          : .257 Weath. Mag
Bullet             : .257, 110, Nosler AccuBond 53742
Useable Case Capaci: 76.606 grain H2O = 4.974 cm³
Cartridge O.A.L. L6: 3.170 inch = 80.52 mm
Barrel Length      : 24.0 inch = 609.6 mm
Powder             : Hodgdon H1000

Predicted data by increasing and decreasing the given charge,
incremented in steps of 1.0% of nominal charge.
CAUTION: Figures exceed maximum and minimum recommended loads !

The program would suggest you may have some room to increase charge, but if you are seeing good accuracy, I don't know that I would mess with your work.

There are some other powders you might wish to consider at some future date.

Cartridge          : .257 Weath. Mag
Bullet             : .257, 110, Nosler AccuBond 53742
Useable Case Capaci: 76.606 grain H2O = 4.974 cm³
Cartridge O.A.L. L6: 3.170 inch = 80.52 mm
Barrel Length      : 24.0 inch = 609.6 mm

Predicted Data for Indicated Charges of the Following Powders.
Matching Maximum Pressure: 63250 psi, or 436 MPa
or a maximum loading ratio or filling of 112 %
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 !

35 loads produced a Loading Ratio below user-defined minimum of 90%. These powders have been skipped.

SenderoAG,

Welcome to the forum. There are many knowledgeable folks here with a wealth of experience. (I am still a novice.)

DrMike who responded above is one of those knowledgeable folks and has provided good information.

There is a dedicated section in this forum on using the Quick Load program. That secions explains how "a number of refinements that can be made to produce very accurate results". I found that section interesting and informative.

Dan

Thanks very much for the help!

It worked very well on two Texas Hill Country white tails.

Hoping to use on Mule deer this fall.

Welcome! And I think your load, with that 110 gr AccuBond likely scooting along at 3300+ fps, and into 5/8" groups should do just dandy on any mule deer!

Regards, Guy

Welcome aboard. As to the 257B; the guy who owns the ranch I guide on has one. It's his go to rifle, he hunts a lot. He thinks it's perfect for Africa as well.
In any event I've personally seen that rifle take mule deer, white tail, coyotes, cow elk, mountain lion and a black bear.
He has owned that rifle for about 40 years, has only ever fired 120 grain Nosler partitions out of it.
I'm very impressed with the cartridge, it will certainly work well on your muley.
