Hi
I’d appreciate a run of QL to show the available powders.
300 WSM Winchester Brass
Primer WLRM
Bullet SGK#2140, 165gn

I’d also like a run with IMR 4350

Thank you!

Useable Case Capaci: 74.353 grain H2O = 4.828 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: 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.

So, now I’m scratching my head. I took my measurements for smk to lands.2.795. Saami says OAL is 2.860. If I load the SMK at 2.860, I can’t come close to feeding a round into the chamber until it’s down to 2.795. Should I give it 0.02” less?

I didn’t expect this. The ogive is differentfron nbt.

Here is your request from the QL thread. I posted in both places since I wasn't sure where you would look for my response.

Code:

Cartridge          : .300 WSM (CIP)
Bullet             : .308, 165, Sierra HPBT 2140

Cartridge O.A.L. L6: 2.860 inch = 72.64 mm
Barrel Length      : 24.0 inch = 609.6 mm

Once I receive my 300 WSM I plan to try this at around 73.0-73.5 grains with the 165 BT for a "light" deer load. I also plan to try the Re26 with 180 gr. AB and 190 gr. ABLR for an elk load.

Thanks Dan. I’ve just printed the recipes from you and Dr Mike.
I’ll set up a ladder test and run the through the chrono. See what I have for accuracy nodes.

Any thoughts on the OAL for the SGK being short compared to Saami?

Reloading manuals indicate various OAL's for their test loads depending on the cartridge and bullet combination. Often those test OALs are shorter than the SAAMI max. length. I used the QL default OAL for this cartridge. In some previous QL projections that DrMike did for me small changes in OAL didn't seem to have dramatic effects on velocity and barrel time (for large capacity bottle neck rifle cartridges). However, I can rerun the projections if you provide a specified OAL. Better yet, if you can load and shoot a few rounds and then provide us with:

- Overflow water capacity of the fired/unresized cases. (an input variable)
- powder used.
- bullet used.
- velocities measured with specific charge weights. (to adjust the burning rate).
- OAL that you used.
- barrel length of your rifle.

Then we can run QL projections that are more specific to your rifle and more specific to your batch of powder and therefore provide more accurate projections. Personally, I do this first before running the ladder test since I can design the ladder test with more accurate information.

mjcmichigan · May 15, 2018

I’ll do that Dan. The ladder test I set was with new cases. I just resized 18 cases, which means a little shoulder bump. I need to find some more RL26. Have 15-20 rounds of powder left. Good stuff. Ready to buy 4 or 8 #
