7mm 168gr Nosler LRAB load data

[IDelkhunter]

Wondering if anyone can help me out? I don't have any of the powders listed on the Nosler website for a 7mm Rem Mag for this bullet (I'm loading for a Ruger #1). Wondering is anyone has used H1000 or Retumbo with this bullet and could recommend starting powder charges and length (distance from lands?).

Thanks,

Marcus

I've had good luck starting with the tested COAL that Nosler lists, EXCEPT their .300 blkout COAL... tis a bit dangerous by 20k psi with my components capacity.

If you want speed, Retumbo is estimated to be a bit faster. Actual results may vary as your components are surely different than what was used for the model, and I am guessing that you have a 26" barrel here. Using Noslers case capacity. If the velocities are close to real world results, I'd venture to say you'll find your top node somewhere near 69.7gr of 1000. Just a SWAG.

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.

Thanks a ton!! I've got to get Quickload...the screen shots are a huge help. Load low and work up....time to start my ladder!

Thanks again....appreciate the help!

It's well worth the investment. And I'm sure the author will appreciate the reward for his work as well.

Good luck with the test!

I shoot a Remington 700 SPS Stainless chambered in 7mm Rem Mag. I custom load 168gr. Nosler Accubond LR and 168gr. Berger VLD hunting bullets. I use 66grs of IMR 7828 and have chronograph velocity of 3000fps. I love this combo, shoots great with a 26" barrel with a twist rate of 1:9.25
