Cartridge : 7 mm Weath. Mag.
Bullet : .284, 150, Nosler BalTip 28150
Useable Case Capaci: 79.421 grain H2O = 5.157 cm³
Cartridge O.A.L. L6: 3.360 inch = 85.34 mm
Barrel Length : 26.0 inch = 660.4 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 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.

Retumbo and RL33 look promising

I'd love to get me hands on some RL33 for tests on several cartridges.

i worked up a load with 7828 and 150 ball tip. I think that I should have used a tougher bullet because here in pa bear and deer are in at the same time. Some of our bears are like 800 pounds and can be shot at close range. I'm having my doubts about the 150 grainer being able to go through a shoulder bone , a layer of fat, and still be able to take out two lungs. What do you think? I'm moving them at 3200.

Impact velocity above 3000 fps becomes somewhat dicey. With the potential for close shops at velocities in excess of 3000, you would be more certain of penetration with either a PT or an AB.

Put the 150 BT into water jugs up close, right outta muzzle, see how it holds up is the best way to verify what it should do. Water is a hard medium and put into jugs up close, it'll hammer less than ideal bullets. I do this with them all. I wanna know, not guess at what will happen up close and far away. Plus, we all like to see the results! :lol:

I will begin handloading for the rifle I recently got a euromark reloader 33 is the best powder out there so far from what I see

I have some of that n 570 ....I'm normally against compressing that much powder but if someone here thinks that it might work I might try it. I'm actually running a an old 7mm mashburn wildcat. I think that the round is basically a necked down 300 win mag. I wasn't sure how to get load data for the mashburn so I had you run the weatherby which is smaller and has free bore. The mashburn is bigger but has no free bore. Are there any 7mm 300 wildcats that quick load has data for?

I measured the case capacity and came up with 86 grains of water from a fired case. Rifle is a 24 inch barreled Remington 700 with the throat cut for a 175 grains Partition so that the coal set so that the bullet set so that the bullet hits the rifling at 3.65 inches.

Here is 7mm WBY data set at 86.00 grains H20 using VN570 powder at 3.65"
Cartridge : 7 mm Weath. Mag.
Bullet : .284, 160, Nosler AccuBond 54932
Useable Case Capaci: 81.283 grain H2O = 5.278 cm³
Cartridge O.A.L. L6: 3.650 inch = 92.71 mm
Barrel Length : 24.0 inch = 609.6 mm
Powder : Vihtavuori N570
Predicted data by increasing and decreasing the given charge,
incremented in steps of 2.0% of nominal charge.
