Those will work fine on your gun, but they will run dirtier than brass ammo. It is definitely overpriced at 2x its actual value.
Market price, gouging, whatever you wanna call it. Lately everything is double the price due to the shortage anyway. But at least its available.
If you really need ammo to shoot and have no other choice, then buy it. I'm sure there are better prices somewhere else, but sometimes it is impossible to find depending on your location. Right now you have to take what you can get. Otherwise, if you don't wanna pay that much for cheap ammo no one is forcing you to..
