Re: Best Hogdon Powder for 7mm WSM??

XP,

I have developed loads for the 7mm WSM with traditional bullet weights and H-4831 worked very well with the lighter bullets but H-1000 worked better with the heavier 150 to 150 class.

For the 180 gr bullets, I would give either H-1000 or Retumbo a try.

Two other powder I would look at would be the new AA Mag Pro and Ram shots Magnum powders. These are both ball powders and are much more stabile then old ball powders in varying temps.

In fact, Ramshot Magnum is very similiar to the Hodgdon Extreme powders in temp change resistance and has a burn rate similar to Retumbo.

The ball powder burns much cooler then any stock powder and will allow a more consistant case fill in this short case.

I would try in this order:

1. Retumbo
2. H-1000
3. RS Magnum
4. AAMagPro

Good Shooting!!

Ernie,
The best powder I have found for the 180 gr. bullet in the 7MMWSM is reloader #25, start with 65 grs and I worked my way up to 67.5 gr with no pressure signs. Muzzle velocity out of a 30" Krieger is 3,150 fps and accuracy is awesome
Hogdon retumbo would also be a good one but in my experiance, which is not that extensive retumbo did not like to be a compressed load as velocity spread increased drasticlly once the bullet started to compress the powder.
FWIW,
