Does anyone make carbide dies for the 223 ?
Are RCBS and Lee dies on par with each other or is one definitely a better die for 223 ?
Yes, the higher end die manufactures make carbide die's for .223, Redding & Dillon to name a couple, but you still MUST use lube, I suggest spray lube. You cannot reload bottle neck cases with out lube, the carbide just makes it so that it resizes easier and doesn't grab the case neck on extraction causing it to pull the shoulder out of spec right after it was just resized!
As for RCBS vs Lee, there is no question RCBS are better dies, however RCBS & Hornady die's are at the lower spectrum of quality dies.
Lee, well they are in a class of their own.. They are CHEAP, that's about all I have to say about them, do they work? Sure, but they arn't going to be consistant like higher quality dies, they arn't going to be as well made, etc. You can take a Lee sizing die and a RCBS resizing die and the RCBS weighs about 2x what the Lee die weighs..
I know there are Lee lovers that will come on and try to convince you how wonderfull Lee die's are, I've had them, I've sold them, and I'll never buy them again.. But if you want to find out the hard way, you are welcome to try them out..
Oh and when someone tells you how great the Lee die's are, ask them how old the Lee die's are that they are using, because many people here that LOVE Lee die's have some that are 20-30+ years old, needless to say they were made better back then, the dies they make today are like many products made today vs 20-30 years ago, they are junk..
