How about Ramshot Big Game in 280 Remington?

[Brian in Montana]

Ever tried it? 139gn Hey BTSP.

I'm only interested in this to fire-form brass to 280AI, but I can't seem to find any load data with is powder for 280 Rem. .270 is available, 7mm-08, and 30-06. I have other powder options, but considering how scarce components are, I'd rather use up this Big Game just because I don't have any particular plans for it. I'd just rather not blow up my face doing it.

So after scouring through what I can find, I think I'll load this next round of brass to be fire-formed with 48gns Big Game and F210 primers. What say yous?

Well, I'm at the range now, I've sent about 20. Happy to report I haven't blown up my face.

And actually, I'm kinda surprised by how accurate this is.

I didn't hear a big boom coming from the direction of Montana, so figured either you didn't try it, or things went well.
