Shortages are real. So is massive price increases. Check the internet for things like .223, .308, etc. You will find that an average 55gr .223 FMJ is selling for around $400/1000. It was around $225/1000 less than a year ago. Even see if you can find any .223. Most of the distributors are out. Shortages of powder and primers, plus brass and bullets do exist. Not sayin that all ammo is gone, but the battle packs of 7.62x51 South African (140 rounds) that I paid $19.95 2 years ago go for around $75 to $85 a pack. But, you can't find any surplus.
If you want 1 box of Remington 30.30, no problem. Wal Mart has it, but look at the price. I was told by a distributor that Remington and Winchester had committed to military production of .223 and .308 in huge quantities. The raw materials are being redirected to mil production away from commercial. I have seen bare shelves at Sportsmans Warehouse and Academy's here in the N Texas area.
If you have unlimited finances, then no problem.
