I think what we are all witnessing is the shortage caused from Covid or the ten other reasons.Apparently this Thread is in regards to the now Extinct 30-06 family of Cartridges. Back in the day 30 years ago perhaps the 280 would have been my favorite of off the Shelf boxed ammo. It's duplicated by the 7x64 which is available very frequently. The 280 didn't have today's high tech bullet technology though it provided adequate accuracy for Hunting. But it faded from shelves long ago. On the wildcat side a Straight 6.5-270 would easily fit the bill only today you can't find any pills now and it's a pure wildcat only custom. Today I would be happy if even the regular 270 was in stock. I digress, none of these cartridges are on the shelves any longer where I live. My favorite all around O6 version Wildcat of my own vision is the 6.5 FMD. Great for Targets or Game & uses the 6.5mm Lapua shoulder design.
The is a reason all the man bun cartridges are on the shelves and that's mostly because the big corporations are building what sells.
Brass is so hard to buy right now in many many case designs.
Let alone, loaded ammo
