The last time I was in my local WalMart here in Maine, there was an 8” x 10” flyer taped to the ammo cabinet, warning people that certain lots of 22LR ammo was being recalled because each round had twice the normal amount of powder in each round.
The flyer listed the lot numbers, and said the rounds could kill or injure the person using a firearm with the defective ammo. I wish I had a copy of that directive....perhaps it’s posted online somewhere.
I got an email from Cabelas on that, listing the lot numbers.
Here is the Remington recall link:
