300 RSAUM

[ImLegend]

I just bought a used model seven in 300 RSAUM, looking for recommendations on reloading dies and sources for once fired brass. Thanks

I'm not sure why you would consider once fired instead of starting with fresh brass and forming it in your chamber?

The little Model Sevens in the RSAUM cartridge are pretty neat in my opinion. I know some will cringe at the notes about factory rifles and quality but these little rifles have worked well when I tested some for clients. And I like the cartridges but I rarely have shot any cartridge I didn't like, well, except for the .270 Win...

Once fired:

You can also run a search on Gunbroker.

I would just get some 7 saum ADG brass and neck up, l believe it will work. You can run into problems with brass fired in another chamber.
The ADG is as good as Lapua.

It would work if it was ever in stock...

Yeah I know, there brass is out of stock for a reason it's worth the wait.
Get on there list.

Buy 7 saum from gunwerks then, it's the same brass with different headstamp. Doesn't come in the nice case box, but in a gunwerks pouch.

Here are a couple of new brass with ok prices.

I have not purchased new 300 SAUM in years as I have several bags of new on the shelf and have found that it lasts almost forever.

I've got the wsm variety in 300, but I'm lacking a 7mm and the 7 saum will probably be my poison. RL26 and a 24"+ barrel gives great fps.

nosler usually has 300 rsaum brass in stores. I bought a buddy of mine a few boxes, was a pretty penny though like 79.99 for a box of 25 lol. I've been trying to buy his off him for almost two years now. Have fun!

 

[L.Sherm]

If you've ever ran Lapua or ADG you'll never want anything else.
ADG is cheaper than Nosler and a whole lot better.

Let me show my ignorance here.
I know what a Mod 7 SAUM is.

What is a 7 RSAUM?

Or 300 RSAUM

The original cartridges were named:

7mm Remington Short Action Ultra Mag

300 Remington Short Action Ultra Mag
