.300 G&A or .300 Broadcreek

[hk940]

I years ago I bought a Ruger #1 in .300 G&A or .300 Broadcreek.
It was a rifle made by the Broadcreek rifle works IIRC in NJ.
It was a 404 Jeffries case neck down to .30.
It has a fluted SS bbl. and a George Vies muzzle brake.
My question is, how close to the Remington .300 ultra mag is this cartridge?
I can't find any info out on the web.
I do know I can't get 100 rounds out of a pound of powder!
It will push a 180g bullet at 3250!
Does any one know of this round?

Look up the Sammi specs for both grab your calipers and your scale. Verify your case vs spec and do a water volume test.

There is nothing on the Sammi web site about either of these rounds.

Your question was how close to the remmington ultra mag are they.... I provided the path to compare them.

Apparently you did not read what I posted. There is no info on either of these on that site, your path provided nothing!

I believe what Ajc1 is saying is look up 300 ultra mag and compare to one of your cases. There are 300 ultra mag drawings on wicki
