Just picked up two 50ct boxes of Remington UMC 223 55gr FMJ from the local Wally World. I always open up my Ammo before I toss it in the plinking box, just to make sure I’m not shorted and that there isn’t anything untoward going on. In one box I noticed this “odd ball” primer and also that while most of the rounds have a brass colored primer, several have silver colored primers. The other box was not so. Every round in it is pretty uniform. This is the first time I’ve encountered a primer like this and also, my first time buying this brand ammunition. Should I toss this round? Report it to Remington? Shoot it as is? Thoughts and opinions appreciated.
