I never heard of the 222 magnum.
Really? You're advocating shooting 222 in 233?If you're using factory ammo, DON'T DO IT!
If you're reloading your own using pistol powders for plinking loads, for example 2.8gr bullseye with 55gr bullets, go ahead, but you're going to end up with short necks! That wouldn't be a bad thing if you're going to use, say, 33gr bullets. HTH
ONLY if its handloaded LOW pressure rounds, NEVER high pressure factory rounds!Really? You're advocating shooting 222 in 233?
I’m just wondering why you would want to take triple deuce brass and pretty much render it useless. I think you could probably trade 100 .222’s for 150 .223’s. They are not easy to come by now.Yup, NEVER shoot a 222 factory round in a 223/5.56 firearm! You're looking for a FUBAR if you do!
