This ultra-cheap steel cased .223 Remington ammo from Tula can be used in a wide range of firearms (it’s a fast moving 55 grain projectile); when you need to have a ton of ammunition and can handle the specific aspects of steel cased ammo. Steel ammunition has been a formidable option for most military clone platforms for decades.
It’s important to understand the sweet sot for this load, because steel is not for everyone every time. You’ll know you are a good candidate for shooting steel ammunition if you want savings over super precision. If you can handle using it only in guns where the tolerances aren’t made for match shooting. If you understand that they function best in heavy sprung firearms that have heavy extraction and ejection cycles. If you want to shoot a lot of rounds and don’t mind it being a bit dirtier. If you come to the range with a clean firearm.
You’ll know you probably won’t want to shoot steel cartridges if you are planning on shooting sub MOA at distances; you can’t stand dirtier powders; your chambering, or other tolerances are super tight or you don’t have a very clean gun. You’ll also find it’s not a perfect round for bolt actions if you are someone who doesn’t want to pay attention too much to details while hooting.
For all other times, or for those who have actually shot steel in their AR/AK/Mil/Clones, this stuff is great fun for a good value.
