I just bought a mannlicher stocked rifle made by Serengeti and chambered in 358 on a neck-expanded 325 WSM case. I guess that would be the same as a 358 WSM? Has anyone loaded for this wildcat? What is the capacity of the 325 WSM case versus say the 358 Win Mag? I'll use 225 or 250gr round nose bullets, for a close-mid-range thumper.

Check out BFG cartridges.

Boomy, it looks like they use the WSSM case to get 358 Win ballistics. This one was using necked-up 325 WSM brass. That should up the performance a bit.

Biebs,

I wish I would have known you wanted something like this. I have one built on a model 70. Great cartridge and I like the 225 gr Nosler BT for it. I'll try and send you my data for it.

Oops
Sorry
Too much info in the brain and needs a brain defrag lol.
What you describe is the 35 Wapiti or 35 Sambar if memory serves me right this time.

35 Sambar. Nice and easy!

Yes, that's what I've found as well...the 35 Sambar from "Down Under". Sam, I appreciate the info.

Hey, I just determined that the case capacity for the 358 Win is 57 grains of H20, and 83 for the 325 WSM. That'll certainly give it some more horsepower!

Biebs,

Sent you email with data. You can get about 2900 fps with a 225 Nosler BT. Flat shooting thumper. Most loads I use are in the 2800 fps range.

Sam

Sam, got it...thanks. I have plenty of Rel 15, so that's the ticket.

When you said 358 Win Mag I assume you mean the 338 Win Mag necked up, just as you are necking up the 325 WSM. The shorter WSM should have about 4 grains less than the Win Mag case necked up, roughly 83 and 87 grains to the top of the neck. For reference, the 35 Whelen is about 73 grains.

Plenty of room to make it sing!

That is getting a bit stiff isn't it?

Someone else sent me a load that does 2,775 with a 250gr Speer, so it's not out of the realm of possibility, I guess.

Just saw this thread. In Australia the 358WSM is called a 35Sambar. I have one made up on a Ruger action.

I am not at home at the moment so do not have load data with me. When I get home I will send youmy loads.

Cheers
