Is there not a concern that the 270WSM will fall out of existence any time in the near future? I have no clue which is why I'm asking. There is a T3 Hunter left handed that I was eyeballing but didn't pull the trigger on it because it was WSM.
As a guy wo seems to like unpopular cartridges (264, 225, 257) I stocked up on brass years ago. Decades later, I still have stockpiles of brass, and can still buy brass and loaded ammo for all of the above.
If you go to a website like Midway, you can buy ammo for literally hundreds of cartridges. Some of which I've never heard of.
The point is that it is very unlikely that ammo/brass will become unavailable, even for relatively unpopular cartridges. If you like the gun/cartridge combo, buy it and worry about more likely problems....like Obama taking the country down the tubes.
