Per Ronny at Olin, they will make it again.... someday. When pressed I got a "maybe next year".
That would do it for me.
Next!
If he doesn't reload, and brass and/or ammo availability in 7 WSM is or is going to become an issue, I'd just get a 7 RM and drive on if I was dead set on a 7 mag. I've in the past pondered a 270 WSM, but I keep reading stuff like this about Winchester will 'eventually' make some, and it makes me squampshus. I reload, so I could get by if I bought a bunch of components and stockpiled and reloaded as necessary, but for a man what doesn't reload, I'd either get a long established caliber or take us reloading as was suggested. This would certainly give you a good excuse to start reloading.
The ammo issue notwithstanding, I've heard good things about the 270, 7mm, and 300 WSM cartridges.
But these guys are right, too...if they are still making 25-20 and 38-40 ammunition, they will still be making 270, 7mm, and 300 WSM ammo for a long time to come.
