30-06 is my favorite cartridge, but almost all 30 caliber cartridges can be loaded to be very effective.
I have a bullet mold that I bought for my 30-30 Winchester (170gr FP) that will work in a pinch in 308 and 30-06. After 2000 fps leading might be an issue depending on the barrel.
But the same can be said for a lot of pistol bullets. Most people do not know that 9MM, 380, 38, 357 all shoot the same diameter (lead) bullet. Some bullet molds will work in all 4 (not ideal for all).
When reloading supplies are low, as they are now, you can always improvise.
It is also one of mine. My most accurate rifle is a 20 year old Browning .30-06 A-Bolt with a BOSS and Leupold scope. I can bench rest groups under 1 inch at 300 yards. (Don't ask me to do that standing, LOL) Every deer that I have shot with it has immediately dropped, literally they didn't even take a step.
One of these days I want to get hold of a Remington 700 long action .300 Win Mag and build a M24 clone ... Just in case I want to reach out and touch someone.
